ABSTRACT:
A rugged fuel rail assembly for holding a plurality of electromechanical fuel injector elements in aligned positions on an internal combustion engine. The beam portion of the fuel rail is comprised of two elongated manifold members with overlapping sides brazed together. One of the manifold members has a series of planar sites with apertures for retaining and precisely aligning a plurality of injector cups. To prevent vapor locks the injector cups are mounted with their cavities in close proximity to the inside of the fuel rail. In addition to being designed for ease of assembly and to provide adequate rigidity without excessive weight, the fuel rail is designed so that various fabricating steps, including the insertion on an internal divider, can be performed from the inside of the rail members prior to assembly.
