Abstract: The present invention relates to a fuel heating system for an engine comprising a cylindrical fuel chamber having a heating line extended centrally through the same and communicatively connected to the engine cooling system. Provided on opposite ends of the fuel chamber are inlet and outlet gas ports that allow fuel to be directed to and into the fuel chamber where the same is heated by the fluid of the engine cooling system passing centrally through the fuel chamber via the heating line. As the fuel is heated up to approximately 160 degrees farenheit, it is then directed from the outlet gas port directly into the carburetor of the engine.
