Fill Pipe RESTRICTOR (Fr)

A fuel tank fill pipe restrictor is used to prohibit introduction of leaded fuel into fuel tank. Unleaded gasoline pump dispensers have a smaller diameter nozzle to fit fuel tank of vehicle requiring use of unleaded fuel (vehicles equipped with catalytic converter).

Visually inspect fill pipe restrictor(s) for tampering (i.e., restrictor is oversize or flapper is non-functional). If vehicle is equipped with an auxiliary fuel tank, ensure auxiliary fuel tank is also equipped with a fill pipe restrictor.
