ABSTRACT:
A fuel rail assembly includes a fuel injector socket having a cylindrical end for receiving an injector and a boxed end for orienting and positioning the injector relative to the engine cylinder. A boxed shape end cap is fitted over the boxed end of the socket thereby supporting the socket. Planar saddle members are disposed on each side of the end cap and radiused edges are fitted to the cylindrical surface of the fuel distribution tube. A jump tube communicates fuel from the fuel distribution tube to the fuel injector socket. A bracket defines a sole plate for the assembly, for attachment to an engine head, and includes a generally planar surface for locating against the planar surface of the saddle members. Components of the fuel rail assembly are first assembled loosely on a fixture, then joined together as the fuel rail assembly.
