Fuel Filler Hose: Description and Operation
FUEL TANK FILLER PIPETo help prevent refueling with leaded fuel, the fuel filler pipe has a built-in restrictor and deflector. The opening of the restrictor will accept only the smaller unleaded gasoline nozzle which must be fully inserted to bypass the deflector. The filler pipe is attached to the tank by a section of hose and two hose clamps. The tank is vented during filling by an internal vent tube inside the filler pipe.
