Volume standard fuel tank is 51 liters, which provides a power reserve of about 600-700 kilometers in a mixed driving cycle.
It is important to note that the tank design includes an integrated fuel pump module, which is located at the rear under the right rear seat. This solution simplifies access to the pump, but creates certain difficulties when dismantling the tank itself. Pump fixed on a flange, which is sealed with a special gasket. Any violation of the flange tightness will lead to loss of fuel and the appearance of a gasoline smell in the cabin.
For proper diagnosis and repair, it is necessary to know the location of all fasteners and connecting pipes. The system uses quick-release fasteners, which over time can “stick” or break when attempting to dismantle. Nissan Almera The G15 has a specific suspension geometry, so when removing the tank, a clear sequence of actions must be followed.
Symptoms of malfunction and leak diagnosis
The first signal about problems with fuel tank There is often a persistent smell of gasoline that appears after stopping the engine or while driving. This symptom should not be ignored, as the leak may be invisible to the eye, but a health and safety hazard. Also a sign of a malfunction is a drop in the fuel level faster than usual or errors on the dashboard related to pressure in the system.
A visual inspection of the underbody of the car may reveal traces of gasoline leaks on fuel tank or on suspension elements. If you notice stains under the machine, stop using it immediately and conduct a detailed inspection. Leaks often occur at the joints of hoses or due to microcracks in the plastic casing, which appear as a result of corrosion of the mounting clamps.
For accurate diagnosis, it is recommended to use visual inspection methods in combination with checking the pressure in the system. Nissan Almera The G15 has a complex ventilation system, so a malfunctioning canister valve can also simulate problems with the tank. It is important to distinguish between these breakdowns so as not to waste time and money replacing the entire tank when the problem lies in a small valve.
Step-by-step instructions for removing and replacing the tank
Removal process fuel tank requires training and compliance with safety precautions. Before starting work, you must completely drain the fuel and disconnect the battery. Removing the tank Nissan Almera G15 is best carried out on a lift or inspection pit, since access to the fasteners from below is extremely limited.
The first step is to disconnect the fuel lines and electrical connectors from the pump module. Use special tools to release the clamps to avoid damaging the fragile plastic of the tubes. After disconnecting all hoses, it is necessary to loosen the mounting clamps holding the tank to the body. An assistant will be needed here, since the tank weighs quite a bit, even when empty.
The next step is to lower the tank using a jack or dolly. Be extremely careful not to damage the underbody of the vehicle or the tank itself. Fuel tank should be lowered smoothly, without sudden jerks. After removal, it can be replaced with a new one or sent for repair if the damage is minor.
☑️ Preparing to replace the tank
Installing a new or refurbished tank is done in the reverse order. Pay special attention to the tightness of all connections. After installation, be sure to check the system for leaks by starting the engine and inspecting the connections under load.

Interaction with the ventilation system and adsorber
Fuel system Nissan Almera The G15 is inextricably linked to the EVAP system. Adsorber plays a key role in the environmental friendliness of the car, preventing the release of harmful fumes into the atmosphere. A malfunction of the canister valve can lead to difficulty starting the engine and increased pressure in the tank.
If you are planning to replace the tank, be sure to check the condition of the tubes going to the adsorber. Clogged or pinched tubes can cause the plastic of the tank to deform due to the pressure difference. Ventilation valve should work properly, providing free access of air during fuel consumption.
When replacing the tank, it is recommended to immediately inspect and, if necessary, replace the fine filter if it is built into the system. This will help extend the life of the new pump and the tank itself. Nissan Almera The G15 has a fairly simple ventilation design, but its reliability directly depends on the cleanliness of all elements.
Original parts and high-quality analogues
Choice between original fuel tank and analogue is always a compromise between price and quality. Original tank from Nissan guarantees a perfect match to the size and quality of the plastic, but its cost can be prohibitively high. There are high-quality analogues on the market that are not inferior to the original in terms of characteristics.
When choosing an analogue, pay attention to the manufacturer and the availability of quality certificates. Cheap Chinese copies often have casting defects and can crack after just a year of use. Plastic must be resistant to gasoline and temperature changes. It is recommended to choose trusted brands that specialize in fuel systems.
It is also worth considering the option of restoring the old tank. Professional services can seal cracks and replace damaged pipes. This solution is suitable if the tank body does not have serious deformations. However a refurbished tank is not recommended for use in vehicles operated in harsh climatic conditions, since the risk of re-damage is higher.
