Abstract: A fuel delivery system for an internal combustion engine of an automobile including a fuel tank, a main fuel line and an exhaust line, wherein fuel flows to the engine initially, until the engine heats up, at which point the fuel is directed through an alternate fuel line to an injector nozzle which disperses the fuel through a corrugated steam line within a heat exchanging chamber defined by an enlarged exhaust housing fitted in line along the exhaust line. Fuel in the corrugated steam line is vaporized by the heat of exhaust gases surrounding the steam line within the heat exchanging chamber. A steam trap receives the partially vaporized fuel from the corrugated steam line and separates vapors from liquid fuel condensation, from which the vapors continue along a steam line leading to a shut-off valve.
