Filling the tanks with fuel is carried out separately in order to fill the tanks completely: first, the main tank is filled (during refueling, fuel is also partially poured into the additional tank), then the additional tank is filled. Fuel is consumed from both tanks in approximately the same way, the tanks work as communicating vessels.
Installation requirements:
- Main tank cover ( without valve, access atm. there is no air in the tank through it)
- Lid additional tank (with valve, access atm. air into the tanks is carried through it)
- Fuel receiver of the main tank (shut off the connection of the tank with the atmosphere, "Air" tube).
Addition: on Scania vehicles (according to theory), an additional tank is consumed first due to discharge, and then the main fuel tank.
System advantages:
Easy to install this wiring diagram. It is not required to purchase a fuel intake for an additional tank. There are no additional connections to the fuel system of the car - accordingly, there is no possibility of its airing. Simplicity and reliability of the system.
System disadvantages:
At very low temperatures there is a possibility of fuel freezing in the banjo bolts and the overflow hose, which will make it impossible for fuel to flow from tank to tank and to balance the pressure in the main tank with atmospheric pressure. If the main tank closes as tightly as possible, and the pressure in it cannot equalize with atmospheric pressure, the tank will be squeezed externally. The tank will shrink inward. With a large number of compression and expansion cycles, the main tank may crack. To avoid this, when the hose freezes, simply open the air to the tank: open the tank’s connection with the atmosphere through the fuel receiver (“Air” tube) or by installing the cover from the additional tank ( with valve, access atm. air into the tanks is carried through it).
Japanese model Mitsubishi SUV Pajero is rightfully considered one of the most functional, unpretentious in use and reliable vehicles that have won the sympathy of millions of drivers around the world. However, at this vehicle there are several standard "sores", one of which is the frequent failure of the fuel tank. Directly about the features of the repair of the Mitsubishi Pajero gas tank and will be discussed.
As a rule, the list of the main causes of gas tank leaks on the Japanese SUV in question includes:
- dirt sticking to containers;
- frequent off-road trips;
- untimely check technical condition.
Initially, it should be noted that the Mitsubishi Pajero developers placed the fuel tank too close to ground clearance, equipping it with an additional plastic protection. Such a measure, as conceived by the creators of the SUV, was supposed to effectively protect the iron container from mechanical damage and extend its service life.
However, in practice, everything turned out differently: dust, dirt, salt deposits began to accumulate in the gap between the plastic casing and the gas tank, causing rapid corrosion of the metal. As a result, the fuel tank leaks even in cars whose service life does not exceed 2-3 years.
Some Mitsubishi Pajero owners use their SUV for cross-country or off-road trips, often hitting various obstacles with the bottom. car tuning, this case will help to modernize it usefully.
Plastic protection in critical cases not only does not save the gas tank from deformation, but also hides traces of serious blows. As a result, microcracks can form, through which fuel begins to seep in small quantities. At the same time, the owner of the car may not notice such a breakdown until the leak becomes global.
After 5-6 years of operation Japanese SUVs Mitsubishi brands experienced experts recommend checking at least once a year technical condition fuel tank.
For this you need:
- drive a car into a pit;
- remove protection;
- estimate appearance tank.
If serious deformations, cracks or signs of corrosion are found, it is best to promptly replace this element.
Advice. You should not cover problem areas with sealing compounds in the hope of long service gas tank, otherwise it can fail at the most inopportune moment, for example, on a deserted highway far from service stations.
All known modifications of fuel tanks
Immediately before replacing the gas tank, it is necessary to select a similar container that will be identical in volume to the original. The following table shows the main characteristics of fuel tanks for Mitsubishi Pajero.
As can be seen from the table, the volume pajero tank recent modifications has significantly decreased. Of course, this does not apply, on which the manufacturer again began to install large fuel tanks.
The reduction in the volume of the gas tank is associated primarily with a decrease in fuel consumption and an increase in standards environmental safety. The cars of the brand under consideration have become less “gluttonous”, while the amount of carbon dioxide produced during the operation of the engine has decreased several times.
The unique video in this article shows what dirt builds up in the tank.
Preparing to remove the gas tank
Before proceeding with the dismantling of the fuel tank, a number of preparatory measures should be performed, in particular:
- drain the fuel;
- remove the rear left wheel;
- remove the protective cover;
- unscrew the supply hoses;
- disconnect connector pins fuel pump and sensors.
It will be extremely difficult to qualitatively change even a half-full fuel tank, therefore, immediately before removal, you can “roll out” the gas tank to almost zero or drain the fuel into a previously prepared container. In the first case after sunbathing warning signal on dashboard(the so-called “gas station” icon) you can drive about 50-70 km, after which a maximum of a couple of liters of fuel will remain in the tank.
At the same time, experienced repairmen do not advise doing this, since small suspended particles often accumulate at the bottom of the gas tank, which can quickly clog the fuel filter. The same is said in the instructions. It is best to carefully unscrew the 12 drain bolt located at the bottom of the tank and drain all gasoline (or diesel fuel).
Note. If all the manipulations to replace the fuel tank are planned to be carried out on a lift, then the wheel can not be removed, since it will not interfere.
After removing the plastic protection, we sequentially loosen the fastening of the clamp on the drainage hose, as well as the hose filler neck. We carry out a similar procedure on the fuel vapor control hoses and fuel return. Don't forget to also disconnect the high pressure hose from fuel filter.
At the final stage, you need to disconnect electrical contacts fuel pump connector and current fuel level sensor. The first chip is located at the top of the tank, and the second is on the right side of the tank (with passenger side vehicle). After making sure that all of the above activities are performed correctly, we proceed to the main part of the replacement.
Removal and repair of the gas tank
The dismantling of the fuel tank on the Mitsubishi Pajero is carried out by unscrewing the four nuts that fix the tank directly to the car frame brackets.
Very often, these elements are subject to corrosion, so they are pre-moistened with a WD40 type compound, which allows you to unscrew all fasteners without any extra effort.
In the case of replacing the old gas tank with a new analogue, all the described procedures are performed in the reverse order, while during the installation process all clamps must be carefully tightened in order to eliminate the possibility of leaks in the future.
If you decide to save your own financial resources and repair the fuel tank, then it does not hurt to listen to useful tips experts:
- For any type of repair of a gas tank on a Mitsubishi Pajero (painting, repairing cracks, removing dents), it is imperative to change the neck gasket through which fuel passes when pouring into the tank;
- It would not be superfluous to additionally replace the gasket of the fuel pump assembly with the fuel level sensor located on it, which, for various reasons, often fails.
To remove the mentioned element, it is necessary to pre-treat with the WD40 composition all the nuts that, during the operation of the vehicle, probably stuck to the landing studs. Next, we take out the old gasket, install a suitable analogue in its place, tighten the fixing nuts and check the tightness of the gas tank.
Crack repair and painting
Recall that if cracks are found on the Mitsubishi Pajero fuel tank, it is categorically not recommended to install it again on vehicle even after extensive renovations. If you nevertheless decide to eliminate leaks in the metal with your own hands, then this can be done either by soldering or by smearing problem areas cold welding. First, do not forget to degrease and dry the surface, after which you can proceed with the repair.
The gas tank is painted only after it has been cleaned of the old coating, for which fine-grained sandpaper is ideal. If corrosion was detected on the container during paint removal, such places are treated with a rust converter, which slows down the destruction of the metal.
Advice. Painting is best done with acrylic enamels, which have good resistance to aggressive acid-base environments. Before installation, the fuel tank is dried, checking for leaks.
Thus, the repair of a gas tank on a Mitsubishi Pajero car is a very responsible event that requires a thoughtful approach, the availability of appropriate knowledge, skills and suitable equipment. The price of a Pajero fuel tank is approximately 50 thousand rubles.
Description of the fuel tank for Pajero 4:
In the manufacture of this fuel tank (REV.2 Reload) for Pajero III-IV, we took into account not only all the experience we have accumulated, but also the wishes of car owners. Fuel tank for Pajero III-IV became not only better looking, but also began to fit on all Pajero since 2000 of release. The whole structure is cut according to our design with a 2mm stainless steel laser, but the bottom of the Pajero fuel tank is cut from a 3mm thick sheet , which will prevent the tank from breaking through when hitting stones, stumps, etc. The fuel tank for the Pajero 4 is designed in such a way that during welding we make only ONE weld inside the tank: we weld the “glass” of the fuel intake to the bottom of the tank (but we will deal with this seam with the next thread)
Partitions are inserted inside the Pajero fuel tank to prevent the appearance of a "wave" when driving. The fuel intake is located inside the "glass" for uninterrupted operation fuel system during vehicle roll
The fuel tank mount for Pajero is the same as the stock tank mount. All fuel equipment is rearranged from the original tank, except for the tubes, they are already on the tank. After welding all the connections, we wash the tank to make sure that there is no process dust. After washing, all tank openings (valves, fuel intake, fuel level sensor, supply and return pipes) are hermetically sealed and the tank is pressurized under a pressure of about 1 atmosphere.
Specifications of the fuel tank for Pajero:
- width: 385 mm
- height: 250 mm
- length: 1540 mm
- weight: 31 kg
- volume: 100 liters (depending on the tank configuration, the volume can vary by 5-7% in any direction)
Pajero 4 Fuel Tank Warranty:
The entire period of ownership of the car, except for mechanical damage.
Installation cost: FOR FREE in our service.

Fuel tank Pajero 3 Pajero4 Stainless steel.
The video provides tips on how to properly connect the Pajero Fuel Tank on various modifications to an SUV. We are talking about stainless steel fuel tanks made in the Republic of Belarus!
Fuel tank Pajero. Long base. Petrol. Fuel tank Pajero. Short base. Petrol Fuel tank Pajero. Long base. Diesel.
Corrosion.
The Pajero fuel tank is a real scourge of the third fourth generation these SUVs. This applies to both petrol and diesel modifications. Despite the fact that the fuel tank is made using the same technology as the tank on the second generation of Pajero without problems. Its unfortunate location on cars of the third and fourth generations leads to corrosion and subsequent leakage.
Leaked immediately after removal. Moreover, it is difficult to seal a leak (repair a fuel tank) with a guaranteed result. Tank corrosion is usually extensive and located in different places! The tank after it is cleaned of rust becomes like a sieve. And on petrol versions it's just dangerous!
Fuel tank Pajero original.
Delamination.
The second but no less significant reason for the failure of the fuel tank, to a greater extent this applies to the third generation Pajero with a 4m41 diesel engine, or rather, with a high-pressure fuel pump from ZEXEL type VRZ (these are all cars from 2000 to 2007), is peeling anti-corrosion coating inner surface fuel tank!
Few owners know that they themselves destroy fuel tanks!
Carried along with the fuel and circulating in the fuel system, zinc particles (which cover the tank from the inside) wear out friction pairs in the fuel pump and injectors. They have a catastrophic effect on the high pressure section. Like sandblasting, producing dosing edges. Which, in turn, leads to premature failure of the injection pump as a whole. There have been cases when Pajero 3 mileage with a replaced with a new original fuel pump, but with a fuel tank not replaced, was 15,000 km. After that, the injection pump needed to be repaired or replaced.
No method of getting rid of the metal abrasive in the fuel, other than replacing the tank, is the solution to the problem!
On the fourth generation Pajero, the problem of tank detachment is not so pronounced due to greater reliability DENSO injection systems. But, premature exit out of service fuel injectors and the pressure control valve in the injection pump, these are “all the same words from the same song”.
We will deliver fuel tanks to any region of Russia, Ukraine and Belarus.
Few of the owners know that they themselves destroy the fuel tanks! From great love for your Pajero, having heard somewhere that weak point their favorite is fuel system. They add various kinds of additives, improvers, cleaners and so on to the tank. Thus, starting the process of destroying the fuel tank, and then the fuel pump!
Tank Destroyer For example, from our experience it is reliably known that this Castrol in combination with diesel fuel, in one or two applications it can damage the coating of the tank!
Fuel additives must not be added!
Relying on our many years of experience in the repair and operation of Mitsubishi Pajero. We declare that when the inner coating of the tank is peeled off, you can forget about the large motor resource of the high-pressure fuel pump. No method of getting rid of metal abrasive in fuel other than replacing the tank is the solution to the problem! Whether it is installing additional filters, cleaning the tank, sandblasting it, painting it with subsequent welding, etc. Checked!
New Pajero fuel tank.
Which one to buy?
Tank epoxy resin glass fiber Poland. When replacing a tank, it must be taken into account that most used fuel tanks offered for sale are already problematic. The seller may not know about the tank defect! And the owner of the diamond changes his exfoliated tank for exactly the same tank, and even worse!
This is where the drain plug should be. It's NOT in plastic! Should not be assigned big hopes and on a plastic tank made in Poland. They are handcrafted from fiberglass and epoxy resin. Often, Polish tanks leak already during installation. True, some owners are lucky and they avoid problems. With almost the same cost of the original tank and the handicraft Polish one, is it worth the risk?

Tanks from China deserve special mention! Not only are they not processed from the inside at all (bare metal)! Already at purchase, pockets of corrosion are observed. So they are different geometric dimensions from original ones. They are 40mm lower. Hence the inability to put a native fuel intake.
Fuel tank China. The washer on the large hole is clearly visible, compensating for the small height of the tank It should also be remembered that gasoline and diesel tanks different. Tanks from the long and short versions of your Pajero are not interchangeable either.
