Fillpipe Restrictor: Description and Operation

To help prevent refueling with leaded fuel, the fuel filler pipe has a built-in restrictor and deflector. The opening in the restrictor will accept only the smaller unleaded gasoline fuel nozzle which must be fully inserted to bypass the deflector. The filler pipe is attached to the tank by a section of hose and a clamp. The tank is vented during filling by an internal vent tube inside the filler pipe.
