Fuel Tank Check Valve




The fuel filler pipe (1) of the fuel tank is equipped with an inlet check valve (2). This fuel tank check valve (2) prevents the fuel from spewing into the fuel filler neck during vehicle refueling. The fuel tank, pipes, and hoses should be checked for any road damage which may result in leakage.
