An apparatus for heating liquid fuel for an internal combustion engine has a heat exchanger equipped with a fileter for removing vapors generated during the heating of the fuel in the heat exchanger. The controller has a finger movable into a passage with a temperature responsive actuator. The hot fuel from the heat exchanger heats the temperature responsive actuator to control the flow of heating fluid to the heat exchanger.

An apparatus for heating liquid fuel for an internal combustion engine having means for supplying the engine with fuel and a cooling system using a fluid to cool the engine comprising: a fuel heater comprising a housing having a first chamber for accommodating hot fluid from the cooling system of the engine, a second chamber for accommodating fuel, and top and bottom end members closing the second chamber, heat conducting wall means separating said first and second chambers whereby the hot fluid heats the fuel in the second chamber, a solid cylindrical core of non-heat conductive material located within the second chamber having an external wall spaced inwardly from said wall means providing passage means adjacent said wall means for the fuel in the second chamber, means connecting the core to said top and bottom end members, a cap mounted on the top member forming a third chamber between said top member and said cap, said top member having passage means connecting the second and third chambers whereby fuel vapors in the second chamber flow into the third chamber, a porous filter operable to allow fuel vapors to flow through the filter and prevent liquid fuel from flowing through the filter mounted on said cap and open to the third chamber and externally of said cap whereby said fuel vapors flow through said filter and externally of said cap and said liquid fuel remains in said third chamber, and a controller for regulating the flow of fluid from the cooling system to the heater in response to the temperature of fuel flowing out of the second chamber of the heater to the means for supplying the engine with fuel.
