ABSTRACT:
A fuel filter housing and fuel heater combination for a fuel-water separator includes, as part of the fuel filter housing, a heater-receiving bore and a protrusion adjacent the heater-receiving bore. The fuel heater is constructed and arranged for inserting into the bore and includes a flange that is attached to the housing for securing the fuel heater in position. The fuel heater includes a notch that is constructed and arranged with a ramp portion. With the fuel heater properly seated, the protrusion inserts into the notch and is seated against the ramp portion. O-ring seal swelling may cause the fuel heater to be difficult to remove and the protrusion cooperates with the ramp portion by way of a camming action to facilitate removal of the fuel heater from the bore under such conditions.
