ABSTRACT:
A fuel heating device comprises an electroconductive inner tube which forms a passageway for fuel to be heated. A heater having a positive coefficient of resistance (PTC) is fixed to the side of the outside surface of this electroconductive inner tube, a resilient electrode contacts this heater from the side of its outside surface, and a first electrically and thermally insulating outer tube is provided around the entire periphery of the aforementioned electroconductive inner tube to cover the aforesaid heater completely for holding the electrode compressed to the heater. A second electrically and thermally insulating outer tube is provided around the entire periphery of the first tube, said second tube including means for mounting the device for use.
