ABSTRACT:
Federal regulations require certain safety features on road vehicles in connection with leakage from gasoline filled devices, such as fuel pumps, wherein only a certain amount of leakage over a specified time period is permitted in a barrier crash or roll over. The invention herein is particularly directed to minimizing leakage so as to conform to federal regulations insofar as fuel pumps are concerned by modification of existing check valves minimizing retooling expense by providing a backup washer spring pressed over an area of the valve disc so as to apply sealing pressure in a pair of spaced concentric areas on the valve seat. This precludes edge curling of the valve disc and ultimate leakage as well as increasing the wear life.
