A device attachable to an internal combustion engine for a motor vehicle having the usual carburetor, air filter and air filter housing, intake manifold, radiator through which an engine coolant is circulated when the engine is running and a source of liquid fuel for the engine. The device includes a fuel vaporizing chamber adapted to fit against the air filter housing and contain a body of the fuel at a predetermined level. The fuel vaporizing chamber is fitted with fluid flow lines for air, engine coolant and engine fuel so arranged and tied in with the engine components to route air into the body of fuel in the chamber and release the air under the surface of the fuel to bubble upwardly and pick up vaporized fuel; route engine coolant through the body of fuel to heat it; route fuel from the engine's fuel source through the body of heated fuel to heat the routed fuel, then route this heated fuel to the carburetor; and route a mixture of fuel vapor enriched air from above the body of liquid fuel in the vaporizing chamber to the intake manifold of the engine where it mixes with an air-fuel mixture from the carburetor.
