Fuel tank cap: replacement and selection

When and why it is necessary to replace fuel tank cap

Manufacturers do not specify exact scheduled replacement terms for this element. A new component is installed in case of thread damaging or sealing element cracking. Moreover, replacement is performed if the cap is deformed.

Careless item usage is the cause of thread defects. In addition the part can become damaged as a result of impact, for instance, during a road accident. And the gasket breaks down due to continuous exploitation of the unit.

“Check Engine” indicator can activate it this element is broken. Also, defects of this component are indicated by the decrease in engine power after warming up. Moreover, a continuous hissing sound occurs when the cap is unscrewed.

It is easy to install this component on your own. In most cases replacement process includes removal of the old cap and installation of a new one. During this you need to assess condition of the fuel tank inlet thread. The tank or the inlet (if it is demountable) is replaced if damage is found.

How to select a fuel tank cap

These components differ from one another by breathing system type.

Thus, the cap can be vented and non-vented. Items of the second type are used if tank ventilation is performed through the inlet. And parts of the first type are used for non-ventilated tanks. Such cap is equipped with a special valve.

Components with and without a lock are available. Caps with cylinder or code locks are quite common. These parts allow to reduce the risk of fuel theft by criminals to the minimum. Components without locks are widely used in cars, in which the tank inlet and the cap are protected by a hatch, that can be opened only from the cabin or is equipped with its own lock.

In order to make a new component isolate fuel securely, purchase an item by a proven company. For example, high-quality caps are presented in the assortment of such brands as Valeo, Febi Bilstein, HELLA.

During ordering of the part, consider your car’s trim level, types of the fuel tank and engine. A properly chosen component will fit by height, outer and inner diameters. Pay attention to the presence and type of locking system installed. Check if there is a fastening cord. Thread type of the component is important for proper installation. Take into account that there are caps with outer and inner thread.
