Abstract

A fuel filtering system having a valve which prevents the flow of fuel in the absence of a fuel filter. The filtering system includes a housing in which a fuel pump is at least partially disposed. A valve mechanism is located on the discharge side of the fuel pump and includes a valve member which is movable between open and closed positions which, respectively, allow and prevent fluid flow through the fuel line. A biasing member is provided for biasing the valve member into the closed position. The valve member is engaged by the mounting of the fuel filter to thereby open the valve mechanism. In the absence of an installed fuel filter, the valve member remains in the closed position to prevent the flow of unfiltered fuel to the engine.
