A fuel rail for an engine fuel injection system comprises a pair of main tubes on opposite sides of the engine. A baffle is disposed within each main tube, dividing the tube into first and second flow channels. Injectors are fed from the first flow channels. A pair of closely adjacent transverse tubes intercept the main tubes at one end of the main tubes. One transverse tube introduces fuel into the first flow channel of each main tube. The fuel flows through these channels and returns via the second flow channels. The other transverse tube carries return fuel from one main tube to the other main tube where it joins the return flow from the other main tube and the flows enter a pressure regulator. The one main tube contains a twist in its baffle so that its injectors are properly communicated to the inlet fuel entering via the one transverse tube.
