Abstract
A diesel fuel heater is provided in the general form of a flexible elongate fluid jacket having sufficient length for wrapping around the diesel fuel filter of a diesel engine. The flexible elongate fluid jacket defines a channel having an inlet and outlet for operatively coupling into the liquid coolant circulating system of the diesel engine. The fluid jacket transfers heat from the circulating liquid coolant to diesel fuel passing through the fuel filter. Furthermore, the fluid jacket and channel are distributed and arranged to cover substantially the entire surface of the circumference of the diesel fuel filter thereby insulating the diesel fuel filter from cold air while maximizing heat transfer. In a preferred example the channel defined by the fluid jacket is in the configuration of an elongate "U" shape in which the legs of the "U" may be wrapped around the circumference of the diesel fuel filter as a single unit.
