VW T3 Rubber Vent Valve Fuel Expansion Tank | N90100501

The rubber vent valve is located on your T3 fuel expansion tank and ensures that the pressure in the system remains correct. This original VW valve (N90100501) prevents your tank from becoming over-pressurised or under-pressurised, which would otherwise lead to leaks and starting problems. After decades of use, the rubber becomes porous and loses its sealing properties. Combine this with a new expansion tank and fuel hoses for a completely refreshed system.
