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 notch, opening into the heater-receiving bore. The notch is constructed and arranged with a ramp portion extending axially into the fuel filter housing. 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 protrusion that inserts into the notch and is seated against the ramp portion when the fuel heater is fully installed. O-ring seal swelling may cause the fuel heater to be locked into the bore 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.
