  • Fuel filter with internal pressure regulator
    Patent number: 6306292
    Abstract: A fuel filter and pressure regulator assembly includes a housing, an inlet tube, an outlet and return tube each made of stainless steel. An annular filter element is disposed within the housing and abuts at one end a pressure regulator element which is mounted within an O-ring retainer that is fixed within the housing. A resilient device, such as a wave washer or O-ring, is compressed as the assembly is assembled. In operation, fuel flows in through the inlet tube which is radially offset at a first end of the housing and into an annular space around the annular filter element. The fuel then flows through the filter media and the filter element and out of the outlet tube which is aligned with a hollow core of the filter media. If fuel pressure is too high, the fuel then flows through the pressure regulator, out of the return tube and back to the fuel tank.
