Device for supplying fuel to an internal combustion engine and transport cooling machine

The invention relates to a device for fuel supply to an internal combustion engine (10), comprising a tank (15) which is designed to receive a liquid fuel, a supply line (17) leading to the internal combustion engine (10), via which fuel reaches the internal combustion engine (10), and a return line (18) leading from the internal combustion engine (10) back to the tank (15), via which excess fuel flows from the internal combustion engine (10) back to the tank. In order to reliably prevent freezing of the fuel in such a device under optimized energy utilization even at low temperatures, the invention proposes to couple the supply line (17) and the return line (18) to one another in a thermally conductive manner, at least in sections.
