If the car engine begins to work unstably (stalls, stalls, has difficulty starting), then there may be several reasons for this, one of them is that it has failed fuel filter. However, to make sure that this particular unit has failed, it is necessary to reliably determine the cause unstable work engine. If the cause of the breakdown turns out to be this part, then the next step is to replace the fuel filter with new unit, taking into account the features different models filters. You can do this at a car service center or yourself. We will look at how to choose and replace the fuel filter yourself below (see the video “Replacing the fuel filter on a VAZ 2110, 2111, 2112” below).
When should you change the fuel filter?
Automotive experts advise replacing fuel filters after 60,000 km, since it is by this time that they become sufficiently clogged. The car, of course, will be able to drive for quite a long time even with a clogged filter, however, in this case, the load on the fuel pump increases, the service life of which begins to decrease. In addition, the engine will begin to malfunction due to incorrect fuel supply. To reliably establish that it is the fuel filter that is broken (clogged), you must do the following:
- Accelerate the car at low speed;
- Press the gas as hard as possible.
If the car engine starts to run jerkily or refuses to accelerate, then the cause of unstable operation is power unit specifically in the filter, that is, replacing the fuel filter is inevitable.
How to choose the right new fuel filter for your car?
KEY PARAMETERS. The choice of fuel filter should be made taking into account the following key parameters:
- Take into account the filtration level: it determines what size particles should be filtered. If you select a filter with low level filtration, then large particles will penetrate into the fuel and, very soon, will damage the engine.
- Take into account the area of the filtration element; the rate of clogging will depend on it: the larger the area, the longer the filter will last, and vice versa;
- The presence or absence of a rubber seal covering the filter inlet: filters without a seal are more difficult to change.
CLEANING LEVEL. It is also necessary to distinguish fuel filters by level of cleaning so that the element can be replaced correctly. So, there are carburetor, injection and diesel fuel filters. Each engine type has a corresponding fuel filter.
- For carburetor systems, the cleaning level is in the range from 15 to 20 microns. Anything smaller will enter the fuel system, however, it will not pose any harm to the engine;
- For injection systems, the cleaning level is in the range from 5 to 10 microns.
- For diesel systems, the purification level is less than 5 microns. IN in this case, not only particles in the fuel are filtered, but also water.
Of course, when buying a new car fuel filter, you need to know the brand of the old filter, as well as the time it was produced. As for replacing the filter with a similar one, but of a different brand, you need to carefully study the possibility of this operation in the car’s operating manual.
How to change the fuel filter yourself?
Before starting work, it is necessary.
Direct replacement Finding a fuel filter on a car starts with determining its location. Most common option its location is under the hood, on top of the engine (almost all diesel engines).
U gasoline engines The fuel filter is located in close proximity to fuel pump.
1. You need to start the car engine.
2. Immediately after the filter is found, you should remove its fuse and wait until the engine stalls itself so that the pressure drops and fuel does not start pouring out.
3. Then remove the terminal from the battery with the “-” sign (to prevent fire).
4. After this, disassemble the diagram of how the dismantled filter is installed in the fuel supply system. Remember the sequence of location of each of the fasteners, as well as washers and gaskets.
5. Having removed the unit from the bracket and wrapped it in a rag, you need to carefully pull it out (the wrapped rag will absorb oil if it leaks).
7. Using new fasteners, connect the filter to the fuel supply system.
8. At this point, replace the fuel filter with new element completed. All that remains is to put the fuse, removed at the very beginning of work, in its original place.
9. Reconnect the negative terminal and start the engine.
Note that an attempt to start the engine the first time usually fails, since the pressure released during dismantling must be restored.

Replacing a car's fuel filter yourself - video
The fuel filter performs important function in the car. Although gasoline appears transparent and clean in appearance, a large amount of any dirt can be dissolved in it, which over time settles at the bottom of the tank or on the fuel filter.
It is recommended to change the filter after 20-40 thousand kilometers. If you do not do this, then all the dirt can get into the fuel deposit, carburetor, and settle on the walls of the liners and pistons. Accordingly, you will face a more complex and expensive repair process. fuel system and the entire engine.
Fits any car model detailed instructions, where the location of the filter is indicated. It can be located near fuel tank, and directly under the hood. Before removing a clogged filter, you need to make sure that there is no pressure in the fuel system. To do this you need:
- remove the fuel pump fuse;
- start the car and wait until it stops working;
- remove the negative terminal of the battery.
After this, you can safely begin removing the old filter. It is usually secured using two clamps or special plastic latches. It is attached to the fuel pipes using fittings. Each model has its own mounting features, so when removing the filter, remember how it was positioned and which tube was screwed to what.
Fuel filters have an arrow indicating which direction the fuel should flow. According to it, you need to install new filter. Figure out which tube comes from the tank and which leads to the fuel pump and to the engine. IN modern models the auto filter simply will not fall into place if it is installed incorrectly.
The filter should come with plastic latches or clamps. Feel free to throw away the old ones because they weaken over time. Insert the fuel pipe fittings and tighten all nuts well. Once the filter is in place, push the pump fuse back and reinstall the negative terminal.
If the engine does not start the first time, it is not a problem; this is a common occurrence after releasing pressure in the fuel system. It will definitely start after a few tries. Check the integrity of the fasteners and whether there are any leaks. Don't forget to wipe everything down well and remove any rags or gloves soaked in fuel.

A car consumes countless amounts of fuel over its life. If we accept average consumption fuel for 10 liters per hundred kilometers, then only for warranty period, equal to 100,000 km for most manufacturers, through the fuel system the car will pass approximately 10,000 liters of fuel. Now let’s imagine how much dirt such an amount of fuel can bring into the power system.
What cars are equipped with a fuel filter?
Fuel filters are also installed on gasoline cars, and for diesel ones. Moreover, the latter have higher requirements for filtration quality than gasoline ones. This is due to the fact that the pressure under which fuel is injected into the diesel cylinders is much greater than that of their gasoline counterparts. And higher pressures require smaller clearances in pumps and injectors; in this case, the particles passed by the filter must be much smaller than the gap so as not to cause wear.
How does a fuel filter work?
Fuel filtration on modern cars is two-stage. In front of the fuel pump, a fine nylon receiving mesh screens out contaminant particles. And then the final screening of particles larger than 10 microns (for gasoline) is carried out by the filter fine cleaning.
Where is the fuel filter installed?
As for the location of the fine filter, automakers' opinions have changed over time. In the beginning, all filters were installed under the car or in the engine compartment and were easily accessible for replacement.
Then (increasingly) the filter began to be installed in the fuel module. This solution, of course, is more compact and convenient for manufacturers of current “disposable” cars. But replacing the filter is either not provided at all, but only as part of the module, or it involves a large amount of work to dismantle and completely disassemble the module. Moreover, the fuel module of some cars cannot be removed without dismantling the tank, and this is an even more ambitious task.
Diesel fuel filter
So far we have been talking about gasoline filters. Diesel fuel filters are always installed separately from the fuel tank, because, in addition to more frequent replacement, they also need water sensors, a water drain plug and, often, a heating system.
What happens if the fuel filter is clogged?
The filters are, of course, damaged by the dirt that gets into the tanks of our cars along with the fuel. And it’s not the oil refineries that are to blame. Fuel can become contaminated during storage and transfer. And the driver will feel the clogging of the fuel filter by the behavior of the car, and first in those modes where the instantaneous fuel consumption of the engine is maximum. These are driving modes with high speeds and intense acceleration. In this case, the engine will lose traction and operate intermittently, although Idling and “quiet” modes everything will look decent.
How often should the fuel filter be changed?
Periodicity regulatory replacement The filter is primarily determined by the vehicle manufacturer. For some manufacturers it is 30,000 km, for others it is 120,000 km. Moreover frequent replacements This is usually recommended by manufacturers who place the filter outside the fuel tank. Change the fuel filter ahead of schedule It is only worth it if you are sure that foreign mechanical particles or a large amount of water have entered the tank. In this case, you should also rinse the tank and possibly replace the fuel pump.
Fuel filters diesel engines It is most difficult in winter: after all, thickened fuel must pass through the filter material. That is why preventive replacement of the filter with diesel car It's better to do it in the fall. This is caused by the fact that throughput filter, already reduced by particulate clogging, will not be sufficient to pass the cold, thickened fuel.
Frequency of replacement of gasoline filters of some manufacturers, thousand km:
- Volkswagen 30 (remote filters)
- Renault 120
- Kia 60
- Hyundai 60
- Lada 30 (remote filters), 120 (built-in filters)
- Refuel at proven, or even better, branded gas stations.
- Try not to pour fuel into the tank immediately after the fuel has been drained from the tanker at a gas station, because the fuel in the tank is agitated and dirt is more likely to get in.
- Do not pour fuel into old, rusty cans.
- Change fuel filters on time - then a malfunction will not catch you on a long journey.
- Wash the fuel intake strainer at the pump inlet: this will extend its service life.
Tell us in the comments if you have encountered problems related to fuel filters? Good luck on the roads everyone!
The fuel filter is one of the most important units for any car. Experienced car enthusiasts should know exactly where the filter is located to improve the technical characteristics of the car. Additional knowledge concerns the operating features of the unit and the need to replace it.
Renault Duster
Motors used for Renault Duster, are distinguished by their unpretentious attitude to the quality of the fuel used. It is possible to use gasoline and diesel fuel. The offered filter is distinguished by a high level of quality, which guarantees the possibility of long-term operation. Most car enthusiasts successfully avoid the need to replace the filter, regardless of the type of fuel used.
Despite the high level of reliability, in some cases the filter still fails, and its replacement becomes mandatory. A car enthusiast can successfully handle the installation of a new unit.
When wondering where the fuel filter is located on a Renault Duster, only one answer can be given: in the fuel pump. The filter is made in the form of a mesh. However, experienced Duster owners It is recommended to take care of installing a full-fledged fuel filter in the engine compartment, since initially a dummy is located in the right place.
Instructions for installing an additional fuel filter
The installation takes place in two stages:
- Use a screwdriver to unscrew the pipe clamps, and use a hexagon to secure the part to the car body.
- At the next stage, the pipes are connected and the filter is removed. It is replaced with a new one, which is installed in the reverse order.
If you plan to install an engine located under the rear seat, it is recommended to initially recline the seat and remove the small hatch. Now you can see the terminal and pipes responsible for supplying power and fuel to the filter. Before carrying out the work, it is recommended to reduce the pressure of the fuel system, since, otherwise, the car owner may face unnecessary risks under the influence of fuel injection. Only after preparatory measures is the filter housing unscrewed and the element dismantled. Then the fuel is drained and the unit is replaced with a new device.
Attention! After this, the car is assembled and the installation is further checked for tightness.
Causes of clogging of the fuel purification unit
Filter clogging can happen with any engine. In most cases, this situation occurs if low-quality or unsuitable fuel with foreign particles is used to refuel the car. Application of quality diesel fuel or gasoline reduces the risks associated with engine failure.
Signs of a clogged filter:
- unstable engine operation at idle or when sharp pressing on the accelerator pedal;
- inability to use the motor on full power;
- regular and sudden installations of the power unit.
If you notice unwanted problems with the Renault Duster, it is best to replace the filter parts. In addition, you can cope with the task yourself.
Renault Logan
An obligatory task is to understand where the fuel filter is located on Renault Logan and the nuances of replacement for the further successful use of cars.
Timeliness Maintenance- This is one of the most important tasks of a car owner. For supporting good condition It is recommended to regularly install a fuel filter on your car. However, where is the fuel filter on Renault Logan? It all depends on the year of manufacture of the car.
- On the first generation Logan (2005-2006), you can find a filter near the gas tank in the place where the fuel pipes exit. For this reason, you need to focus on right side district rear wheel.
- For cars manufactured after the third quarter of 2006, the fuel filter is located directly in the gas tank in the same place where the pump can be found. This option guarantees maximum level reliability, as a result of which the car is ready to serve successfully and properly.
Understanding where the fuel filter is located on Renault Logan allows you to navigate the further replacement process.
Features of replacing the fuel filter
The first mandatory step is preparing to install a new fuel filter. During operation of any engine, the fuel is under constant pressure, which remains for two to three hours after the power unit is stopped. It is best to replace only after a couple of hours have passed. If there is no possibility of waiting for a favorable moment, the pressure from the fuel line must be relieved.
How to reduce excessively high blood pressure:
- At the very beginning, raise the rear seat and disconnect the wiring block on the vehicle’s fuel pump.
- Then they start the engine and wait for the remaining fuel to burn out.
- After the engine has stalled on its own, turn it with the starter for a few seconds. It is this stage that marks a decrease in operating pressure.
- Now you can disconnect the negative terminal from the battery.
- After the pressure has been relieved, dismantling can be carried out.
To replace the fuel filter, work is done on both sides using fittings secured with tips and red and green clips. The order in which the pipes are removed does not play any role, but it is best to focus on the arrow located on the filter housing. The arrow indicates the direction of the fuel. Installation is carried out in the reverse order of dismantling.
After replacing all components of the fuel wire and terminals to the battery, fill the system with fuel. To do this, turn on the ignition for a few seconds. During short-term operation of the pump, check the tightness of the filter, pipes, and clamps. Regular replacement of all units guarantees the possibility of successful and safe travels by car, because it is assumed that the reliability of the technical system will be maintained.
It is important to remember the purpose of the fuel filter. So, this device required for successful purification of gasoline or diesel from the following components:
- sediments;
- dirt;
- rust.
Pay attention to low quality fuel used, you can understand how important it becomes to use a serviceable and functional filter. The manufacturer recommends replacement procedures every 120 thousand kilometers. However, if used low quality fuel, the event is recommended every 50-60 thousand kilometers.
Chevrolet Cruze
Chevrolet Cruze- one of the most popular cars. It is this machine that has earned an ideal reputation thanks to high level reliability and optimal technical specifications. However, in order to reap its full benefits, it is extremely important to maintain the fuel system perfect condition.
So, where is the fuel filter on a Chevrolet Cruze and what approach is required to keep it in good condition? It is interesting to note that Chevrolet does not install such an item as a fuel filter. The Cruze's full-fledged unit is replaced by a regular mesh, responsible for filtering the fuel used. The mesh can be roughly called a fuel filter.
Automotive manufacturer notes that the fuel pump is installed for the entire life of the vehicle. For this reason, its replacement is impractical. Despite this, the low quality of diesel fuel and gasoline in Russia makes it necessary to know where the fuel filter is and how to change it.
When to change the fuel filter mesh
- lack of coordinated engine operation;
- loss of power from the power unit and a feeling of “failures” when pressing the gas pedal;
- reduction in machine dynamics;
- jerking when pressing the gas pedal sharply.
All four of the above signs are enough to think about replacing the filter mesh. In most cases, installing a new mesh is recommended after 60 thousand kilometers.
How to replace
Before carrying out the activity yourself, it is recommended to carefully study the instructions in order to know not only where the fuel filter is located, but also to successfully cope with the replacement.
The first stage is preparation. Only after appropriate preparatory measures can the procedure for replacing the filter (mesh) be carried out. It is best to use an original product from Chevrolet, but you can also choose domestic products. Considering different opinions, you can understand that the choice depends only on the preferences of the car enthusiast. Domestic filter meshes are always produced taking into account the features Russian fuel, so their service can be long and successful.
It is recommended to carry out basic work before releasing pressure in the fuel system. To do this, you need to turn off the ignition and remove the fuse from the unit. After completing the task, you need to let the motor run for some time. Only after the car stalls can the pressure be released.
So, how to carry out further measures to replace the filter:
- The Chevrolet Cruze does not have a hatch for the fuel pump, so in order to get to it, you will have to remove the entire tank.
- Wires are connected to the pump using a harness, which must be carefully disconnected.
- Now you will be able to see several pipes through which fuel enters and exits the pump. The pipes with clamps are disconnected with a flat screwdriver.
- The next step is to disconnect the fuel pump cover, acting extremely carefully and turning the locking disc counterclockwise. Unscrew the fixing disk, and then the pump.
- There are connectors on the fuel pump that need to be disconnected. In addition, four latches are pressed off the body.
- The top part of the fuel pump should be removed without any problems.
- If engine problems are caused by the filter mesh, you can note the presence of dirt. Cleaning the part will not help, so the mesh will have to be replaced and all parts installed in the reverse order.
You can even successfully replace the filter mesh on a Chevrolet Cruze yourself!
Kia Rio
One of the most important questions is where is the fuel filter on the Kia Rio? This question is asked by many car enthusiasts, because Kia Rio is convenient and decent modern car, capable of delighting with its dynamics. For successful use of the engine, it is recommended to replace it every 2 years or every 60 thousand kilometers traveled. It is advisable to check the fuel filter once a year or every 30 thousand kilometers. If you ignore the advice, unwanted particles from the fuel will contaminate the injectors and worsen technical specifications cars. In addition, the symptoms of a dirty fuel filter lead to disruption of the functionality of the engine, which is forced to work for wear and tear.
Self-replacement options
The event can be carried out independently or at a service station. In the first case, you will be able to save money, but in the second case, you will still have to pay for the procedure. It should be noted compact dimensions fuel filter and efficiency of the procedure.
The first stage is reducing the pressure of the fuel system:
- turning on the neutral position of the gearbox and hand brake;
- removing the pillow rear seat, hatch covers from the fuel tank;
- releasing the latch to disconnect the wire block;
- starting the engine to generate remaining fuel;
- turning on the starter for a few seconds.
Now you can remove the old fuel filter:
- the clamps are carefully compressed;
- the pipelines are disconnected from the filter;
- release the clamp;
- pull out the filter.
Now you need to install a new filter, performing all the steps in reverse order.
If, nevertheless, cooperation with a service station becomes the preferred option, you need to count on a minimum price of 1,500 rubles. This cost is due to the ease and speed of the work.
Toyota Corolla
Toyota Corolla- this is a car in which the fuel filter guarantees uninterrupted and long-lasting engine service. The design of the original device differs from other variations of the device. At the same time, the performance features always depend on the Corolla modification.
It is possible to carry out replacement measures every 50-100 thousand kilometers.
So, what is the difference between original fuel filters for Toyota Corolla?
- the device is based on honeycombs, which guarantee successful fuel filtration;
- the plastic housing of the fuel supply unit is the basis of the filter element (thus, when wondering where the fuel filter is located on a Toyota Corolla, you can note that its location is the fuel unit);
- For fuel purification, traditional paper parts are used, as well as fiberglass and polyester.
Even modern and reliable use of a filter does not guarantee long service life. According to the manufacturer's recommendation, replacement is recommended every 80 thousand kilometers, but this information is approximate.
On domestic market can offer at least three types of fuel filter for Toyota Corolla. Products come from the original brand, Chinese and Korean manufacturer. In this case, you need to choose a fuel filter that is suitable for Toyota car Corolla, taking into account the model type (before 2007 or after). Until 2007 it is envisaged mandatory replacement fuel pump with filter; since 2008, separate installation of filter parts is allowed.
Ford Focus III
IN Ford Focus III fuel filter is installed by a fuel pump, which is located in the tank. This tricky arrangement immediately makes it difficult to replace the device yourself.
In this case, you need to know not only where the Ford Focus 3 fuel filter is located, but also the features of its design. The car has a non-separable fuel pump, so it is necessary to replace not only the filter mesh, but also the pump. Many car enthusiasts go against the American manufacturer, but such work is always risky and it is still better to rely on official recommendations.
So, knowing where the fuel filter is located on the car, you can provide for the possibility of self-replacement and take care to clearly understand all the advice and each stage of the work ahead. Only proper maintenance will support technical condition any car in perfect order.
In Russia today, the situation is such that some gas stations do not have very clean fuel, therefore, given the conditions of our country, the filtration of fuel already inside the car, which is carried out using a fuel pump filter, is especially acute. Therefore, the fuel filter should be changed a little more often than required by the regulations of your car. Because fuel injectors have very tiny holes, the fuel filter is used to remove even the smallest contaminants. On average, the fuel filter should be changed at least every 100 thousand kilometers or 3 years of car operation. But for some car models, the instructions require replacing the fuel filter much more often.
So, how to change the fuel filter in a car? We will look at the most common replacement scheme air filter car when the filter is not located inside. This scheme is suitable for replacing the fuel filter of many models of such brands as Toyota, VAZ, Renault, Nissan, Ford, Kia, Hyundai, Opel and others.
To replace the fuel filter we need the following tools:
- set of wrenches;
- (may be required) special tool to remove fittings when replacing fuel filter;
- pliers;
- protective gloves;
- safety glasses;
- screwdriver.
So, let's change the fuel filter! Below you can see visual replacement fuel filter in different models.
Part 1: remove the old fuel filter for replacement
Step 1: Locate the fuel filter. Typically, the fuel filter will be located under the vehicle - either under the seat right next to the fuel tank, or it will be accessible from under the bottom of the car. Less commonly, it may be located in the engine compartment. In this case, look for it near the wall separating engine compartment from the car interior.
The fuel filter may also be located inside the fuel tank - in this case you will need to remove the small tank hatch and pull it out along with the fuel pump. In this case, you will need to stock up on a special sealant for the subsequent installation of the hatch cover with the replaced fuel filter.
Step 2: Unscrew the fuel tank cap to relieve the pressure in the fuel supply system.
Step 3: Disconnect the fuel line. Use two wrenches to disconnect the fuel lines from the filter. Place one wrench on the fuel filter fitting and the other on the flare nut. Turn the fuel line fitting counterclockwise while holding the filter with another wrench.
Note: this method for disconnecting fuel lines varies between vehicle models. Some vehicles are equipped with quick release fittings that must be removed using special tool. Some vehicles have fuel lines that are held on by clamps that can be removed using pliers or a screwdriver.
Step 4: Now remove the fuel filter itself from the brackets. Loosen the fasteners using a ratchet or wrench of the appropriate size.
Step 5: Remove the fuel filter. Once the fasteners have been removed, remove the fuel filter from the bracket. Throw away the old fuel filter.
Part 2: Install a New Fuel Filter
Step 1: Install the new fuel filter into the mounting bracket. Then tighten it onto the bracket with the same fasteners in the reverse order of removing the filter.
Step 2: Install fuel lines. Push the fuel lines onto the filter by hand. Place a wrench on the fuel filter, and another wrench on the flare nut. Turn the second wrench clockwise until it holds the filter tightly with the other wrench.
Step 3: Screw the fuel tank cap back into place.
Step 4: Check the operation of the vehicle. Start the engine and check the area around the fuel filter for leaks. If you find a fuel leak, recheck the fuel filter, fuel lines and all fittings.
