A valved unit to control introduction of liquid fuel and venting of vaporous fuel relative to a vehicle fuel tank which unit is mounted on to the tank wall to effectively seal and isolate the tank downstream from a filler tube and related fuel delivery hoses. Tank closure is normally maintained by a closure spring which is overcome by introduction of fuel into the tank which allows movement of the inlet closure valve from its seated closed position and simultaneously opens an associated vaporous fuel vent control valve. When introduction of fuel is terminated, a spring returns the two valve elements back to their closed and sealed positions.

A fuel fill and vapor venting valve unit for a tank liquid fuel comprising a base plate directly attached to said tank, said base plate having a first valve housing extending therefrom disposed within the tank, the housing includes a fuel inlet which routes liquid fuel into the tank through said housing, a first valve element operatively mounted within said housing for movement between a closed position in said housing so that said liquid fuel is confined within the tank and an open position in said housing so that liquid fuel can be added into the tank through said fuel inlet and said housing, and spring means operatively mounted within said housing for urging said valve element to said closed position and for yielding in response to displacement of the valve element from the closed position to an open position by the force of liquid fuel exerted thereon when routed into the tank through said inlet and said housing, said base plate further having a second valve housing extending therefrom in side-by-side disposition within the tank with respect to said first valve housing, a second valve element mounted within the second housing movable between an open position in which the tank is vented and a closed position in which said tank is closed, a linkage lever pivotally mounted within said tank operatively interconnecting said valve elements to one another so that the opening of said first valve element from the force of liquid fluid being routed into said tank effects the opening of said second valve element and the subsequent closure of said first valve element effects the closure of said second valve element.
