This intermediate rubber is an essential component designed for the filler neck of a metal fuel tank in the iconic Citroën 2CV. The rubber provides a reliable seal between the fuel tank and the filler neck, preventing fuel leakage and evaporation. This not only increases the fuel supply efficiency but also contributes to the vehicle's safety. Made from high-quality rubber, this part offers durable resistance to gasoline and temperature fluctuations. Essential for anyone looking to maintain the authentic experience of the 2CV and avoid issues on the road.
