A fuel supply system is provided with a heat exchanger disposed in a generally planer cavity within a base. A manifold attaches to the base and contains the generally planer cavity. A heat exchanger, which comprises a fuel conduit, is disposed within the cavity. As fuel flows from a fuel pump to a fuel injection system of an internal combustion engine, it passes through the fuel conduit which is bathed in a flow of coolant. Some of the fuel flows directly from the fuel conduit to the fuel injection system, but excess fuel flows through a pressure regulator and a filter before being passed through the pump again to recirculate through the fuel conduit of the cooler. The quantity of fuel stored within the volume of the fuel supply system is significantly reduced because of the location of the various components and the fact that the components, such as the filter, regulator, and pump are attached directly to the base of the system. This reduces the need for interconnecting tubing or hoses and the resulting reduced amount of fuel stored in the system can be cooled much more rapidly when the engine is restarted.
