Claim Text:
1. A heated fuel injector for supplying fuel to a fuel consuming device, said fuel injector comprising: a fuel inlet for receiving fuel; a fuel outlet for dispensing fuel from said fuel injector; a fuel injector body extending along an axis and fluidly connecting said fuel inlet to said fuel outlet, such that fuel flows within said fuel injector body; a cylindrical heating element radially surrounding said fuel injector body which operates to heat fuel flowing through said fuel injector body over a range spanning a colder temperature to a hotter temperature, with an annular space defined between said heating element and said fuel injector body sufficiently large to accommodate thermally caused radial differential expansion between said fuel injector body and heating element, and; a conductive material substantially filling said annular space and having a sufficiently low melting point to be a liquid as said heating element operates to thereby substantially prevent transfer of mechanical stress to said heating element due to said radial differential expansion.
