The fuel tank filler pipe and the gravity valve are made as a single plastic unit and are connected to the tank by three rubber hoses of different diameters.

The larger diameter hose is used to fill the fuel, the medium diameter hose is used to vent the fuel tank, and the smaller one is used to drain fuel condensate from the gravity valve into the tank.

The ventilation hose is designed to remove air displaced from the tank during refueling and to remove gasoline vapors through the gravity valve into the adsorber of the fuel vapor recovery system.

When the car rolls over, the gravity valve prevents fuel from getting from the tank into the engine compartment through the fuel vapor supply hose to the adsorber.

When dismantling the filler pipe, the tank must not be completely filled with fuel.
