A closed chamber is provided for containing evaporative liquid fuel for a combustion engine and fuel supply structure is operatively associated with the chamber for maintaining a predetermined general level of liquid fuel in the chamber. The chamber includes engine induction air inlet structure opening thereinto below the aforementioned liquid level and a vaporized fuel and air outlet opening outwardly of the chamber from a level above the predetermined liquid fuel level. Duct structure is provided including an inlet portion communicated with the vaporized fuel and air outlet and an outlet end for communication with the induction passags of a combustion engine. Further, an air conditioner evaporator-type heat exchanger is provided and liquid fuel conduit and pump structure is operatively associated with the chamber and heat exchanger for circulating fuel within the chamber through the heat exchanger. Also, both the air inlet and air and fuel outlet for the chamber include valve structure operative during periods of non-use of the associated combustion engine for closing the chamber inlet and outlet, a warning system is provided for indicating a drop of liquid level within the chamber below the aforementioned predetermined level and water sensing structure is provided for sensing a build up of water in the bottom of the chamber.
