An apparatus for supplying cooled fuel to the fuel injection valves of a fuel injected internal combustion engine. In the engine, there is a distribution tube having a fuel passage for fuel and a coolant passage for a cooling medium such as water or air. The fuel passage is provided in close proximity to the coolant passage, whereby the fuel in the fuel passage is cooled by the coolant in the coolant passage. Consequently, the cooled fuel is supplied to fuel injection valves.
