A valve for use in a vehicle fuel line between a fuel tank and a fuel pump for preventing fluid from flowing from the fuel tank to the carburetor of an engine when the fuel pump is not functioning and for allowing such fuel to pass through the fuel line to the fuel pump and carburetor when the fuel pump is in operation. A valve assembly within a chamber of the valve is biased to a closed position, but is movable to an open position in response to a suction effect from the fuel pump. The valve assembly includes a novel structure for insuring a positive seal when the valve is closed.
