ABSTRACT:
A vapor vent valve for automotive fuel tanks is provided with bayonet-insertion, turn-to-lock mounting structure mating with a recessed opening in the top wall of a vehicle fuel tank. An O-ring mounted on the valve body provides a fluid-tight radial compression seal between the valve body and the fuel tank wall to prevent leakage of fuel and fuel vapor therebetween. An annular plastic spring washer is disposed between a top flange of the valve and the top wall of the tank to create an axial tension between valve and tank and also to act as an external weather seal. The spring has an integral means to prevent over-center flexing and shape inversion.
