A heater (16) for heating diesel fuel in a fuel filter (15) to prevent jelling of the diesel fuel is disclosed. The heater (16) includes a receptacle (34) having an open top and an internal cavity (35). The fuel filter (15) is positioned in the internal cavity (35). A first O-ring (36) secured to the receptacle (34) sealingly engages the fuel filter (15) to close the open top. Conduit means connect the internal cavity (35) to a coolant system (31). The conduit means includes an inlet conduit (32) having a first end (32a) which may be connected to for fluid communication with the coolant system (31) and a second end (32b) secured to the receptacle (34) and in fluid communication with the internal cavity (35). The outlet conduit (33) has a first end (33a) which may be connected in fluid communication with the liquid coolant system (31) and a second end (33b) cooperatively connected to the receptacle (34) and in fluid communication with the internal cavity (35). The heated liquid in the coolant system (31) passes through the inlet conduit into the internal cavity (35), adjacent the fuel filter (15) heating the diesel fuel in the fuel filter (15). The heated liquid exits the receptacle (34) through the outlet conduit (33). Means for fastening the receptacle (34) to the fuel filter (15) is also provided.
