Original keyed fuel filler cap for VOLKSWAGEN Combi Bay Window (08/1973-07/1979)

The fuel tank cap (or fuel reservoir cap) is an important element of the car, not only to prevent fuel from evaporating but also to ensure the vehicle's safety. It serves to hermetically seal the opening of the fuel tank and can also play a role in the tank's ventilation system. It prevents fuel leaks, especially in the event of an accident or jolts, while maintaining a constant pressure in the tank. It prevents foreign objects or water from entering the tank, which could damage the engine or compromise the quality of the fuel. The cap can wear out over time, especially its rubber seal, which can lead to fuel or vapor leaks. If the cap is defective (cracks, worn seal, broken closure mechanism), it is advisable to replace it. A persistent smell of gasoline, even after refueling, can be caused by a tank cap that no longer closes properly. A defective tank cap can not only lead to fuel losses or polluting emissions, so do not neglect this detail! This high-quality German equivalent fuel tank cap fits VW Combi Bay Window from 08/1973 to 07/1979 since chassis no. 214 2000 001. Metal model, delivered with 2 keys.
