ABSTRACT:
A combination fuel pressure regulator and fuel filter apparatus for vehicle fuel systems wherein the pressure regulator telescopes into the fuel filter and wherein the two parts are separable and independently replaceable. The fuel filter is operably disposed between an inlet supply tube and an outlet tube for filtering impurities from fuel passing therethrough. A valve in fluid communication with the inlet tube is provided with a regulator for causing flow to be short circuited back into the fuel supply tank when the pressure in the fuel outlet exceeds a predetermined level. The valve is biased to a closed position and will remain closed when the pressure on the clean side of the filter is below the predetermined pressure whereby all of the fuel in the inlet tube will pass through the filter when the pressure in the fluid outlet is below the predetermined pressure.
