The fuel tank is an important structural component of the fuel system and is needed in order to ensure the safety of storing a certain amount of fuel. Apart from that, it prevents the leakage of fuel and limits the amount of exhausted gases when vaporizing. Usually, it is installed in front of the rear axle under the rear seat, in order to avoid the deformation area in case of an impact from behind. Its self-contained volume provides a run of 600 km. The fuel tank is mounted on the body with tank bands, and on its lower part can be installed metal protection against damage. To prevent heating of the fuel tank from the elements of the exhaust system, it is provided with heat-insulation gaskets.

Regarding the material, fuel tanks are made from aluminum, steel or plastic. The most popular material is now considered high-density polyethylene, which advantage consists in best use of installation space. Thanks to this material, fuel tanks can have any shape, thus maximizing its volume. Apart from that, plastic does not get affected by corrosion. Considering the fact that the fuel tank walls are permeable to hydrocarbons on a molecular level, the multi-layer material prevents micro-leakage of fuel. Some fuel tanks are also covered with fluorine, which also prevents leakage.

In order to optimize available space, new car manufacturers develop an individual fuel tank. Moreover, even if the cars are of the same model, their tanks can vary significantly. It depends on the body type of the car, engine type, as well as fuel, air conditioning and injection systems. If your tank has suffered from an accident or deformed due to leaks and other circumstances, you need to change the tank. It is pretty simple to be made: order a fuel tank for your vehicle brand and model on our web-site. In our online shop you will also find oil filters, fixed rollers or door handles.

What you should know about fuel tank replacement: lifetime limits, common defects and their signs, tips and recommendations

Lifetime of the fuel tank is not limited by specific terms. Often the component serves faultlessly during the whole car operation time. The component is replaced by necessity: at body perforation or deformation, in case of significant corrosive damaging.

In the first place, presence of fuel tank damages is indicated by strong smell of fuel inside of the passenger compartment and excessive fuel consumption. Also you should visually inspect the part in case of troubled engine start, unstable idle run, or if you found fuel leakages near the tank. A defect can be detected by component visual check.

Replacement of the car fuel tank should be performed at a service station, as it is quite a laborious process, requiring experience. For removal and installation of the part, you will need an inspection pit or platform and a set of special tools. Before starting the procedure, fuel is drained, power supply from the fuel pump is disconnected, the fuel level sensor and fuel hoses are disconnected. Then, fuel tank fasteners are unscrewed and the part is carefully lowered down. During mounting it is important to make sure that hoses and pipes are not kinked. And hermeticity and reliability of all connections should be checked after finishing of installation.
