NON-EXPULSIVE FUEL FILLER ASSEMBLY ABSTRACT A fuel filler assembly (10) for a fuel tank (12) of a vehicle including a filler tube (14) for directing fuel to the tank (12) and a vent tube (15). The vent tube (15) is closed by a float valve (24) when the tank is filled to capacity and an equalizing port (27) is provided in the vent tube (15) to balance the pressure between the upper portion of the filler neck and the vapor dome area of the tank. When pressure is relieved either by removing the filler cap or by opening of a filler cap relief valve, a relief valve (25) located above the float valve (24) and within the vapor dome of the fuel tank operates to allow pressure relief from the vapor dome of the fuel tank. A check valve (20) is provided in the filler tube (14) at the fuel tank (12). The check valve (20) in the filler tube (14) features a valve element (38) having cylindrical sides (39) and a hemispherical end (41) which is received in a housing (32) having cylindrical walls (34) and an annular seat (40) against which the hemispherical end (41) of the valve element (38) seals. The check valve (20) in the filler tube (14) is spring biased into a closed position with a force less than that required to automatically shutoff fuel dispensing.
