A system (10) for preheating fuel in a fuel tank (16) for an internal combustion engine. The system (10) includes a heat exchanger (12) for transferring heat from a heated fluid to the fuel. The heat exchanger (12) includes a fuel tube (32) being surrounded by the heated fluid for further heating of the fuel prior to its entering the fuel line of the vehicle or other device in which the system is installed. In the preferred embodiment, the heat exchanger (12) is installed through an access opening (14) normally provided in fuel tanks used in diesel engine-powered over-the-road trucks. A flange (18) is provided for securing the heat exchanger (12) to the flange (20) which surrounds the opening (14) in the fuel tank (16).
