The filling pipe of the fuel tank and the gravity valve are made of plastic and connected to the tank with three rubber hoses of different diameters

The larger diameter hose is used for filling fuel, the middle one is for venting the fuel tank, and the smaller one is for draining fuel condensate from the gravity valve into the tank.

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

When the vehicle rolls over, the gravity valve prevents fuel from entering the engine compartment through the fuel vapor supply hose to the adsorber.

When dismantling the filling pipe, it is necessary that the tank is not completely filled with fuel.
