This patent describes a compact fuel rail for a V-engine which has fuel injector openings arranged in two lines. The fuel rail consists of an elongated body mountable above and between the lines and has axially spaced fuel injector sockets and a pair of axially extending fuel passages, the fuel passages being interconnected and one of the passages intersecting the sockets for supplying fuel to the sockets. At least one end of the body has a circular recess intersected by and encompassing the associated ends of the fuel passages. One of the passages is circular in cross section, a circular plug received in the circular cross section passage adjacent to the recess limits interconnection of the passages through the recess, a circular plug received in and sealing the recess provides a closure for the associated ends of the passages. Some of the sockets extending transversely leftwardly and downwardly toward one of the lines. The remainder of the sockets extending transversely rightwardly and downwardly toward the other of the lines, each of the sockets receives a fuel injector suitable for delivering fuel from its socket through one of the openings. Each of the injectors have a clip for securing the injector to the fuel rail. Each of the injectors further have a tip adapted to be received in one of the openings, and a device for securing the fuel rail to the engine above and between the lines by exerting only a downward force on the body to thereby retain the injectors between the fuel rail and the engine.
