An apparatus is disclosed for cooling fuel by means of the cold side of a thermoelectric unit just prior to entry of the fuel into the fuel delivery components (injectors, carburetors and throttle bodies). An excess of cooling is supplied sufficient to cool the fuel delivery components so as to provide an additional buffer of cooling for the fuel and to prevent substantial re-absorption of heat after the fuel is cooled. The hot side of the thermoelectric unit is cooled by a secondary cooling fluid system separate and distinct from the principal cooling fluid system for the engine block. In one embodiment, excess fuel is shunted by a fuel bypass pressure regulator to a fuel bypass line, and the excess fuel is the cooling fluid which is returned to the fuel tank.
