A fuel injection system for internal combustion engines with multiple fuel injection valves. The fuel injection system includes a dimensionally stable fuel manifold distributor with nipple plug connections, by means of which the fuel is directed to the individual injection valves. The fuel manifold distributor is disposed over the injection valves and is pitched with respect to the horizontal, with a fuel injection connection located at the lowest point of said manifold and connected to the pressure side of a fuel pump, with a return line connection provided at the highest point of the fuel manifold distributor leading to a return flow line, over which a portion of the fuel may be redirected to a pressure regulator and from there to the suction side of a fuel tank to which the fuel pump is connected. The fuel manifold distributor design described here makes it possible for the vapor lock bubbles that are formed to enter the return flow line after the hot internal combustion engine has been switched off, and to be directed to the suction side of the fuel pump when said internal combustion engine is restarted, thus making it possible to avoid problems in starting.
