A relatively large auxiliary fuel supply tank is carried by a trailer of a tractor-trailer combination. A fuel supply system provides for a transfer of fuel from the large, separate tank of the trailer to a point of consumption for an engine carried by the tractor of the combination. In one embodiment, fuel can be transferred from the separate fuel tank to the engine itself by a conventional fuel pump carried by the engine, and in another embodiment fuel can be transferred from the separate fuel tank into one or more small-capacity fuel tanks carried by the tractor. Automatic control means are provided for maintaining a desired level of fuel in the small-capacity fuel tanks in the second embodiment.
