Abstract

A fuel delivery system for an internal combustion engine having a molded plastic fuel rail with an electrical bus molded therein. The fuel rail has a keying feature which allows orientation of the fuel injector relative to the fuel rail when the fuel injector is inserted into the fuel rail. Further, a locking device is provided to lock the fuel injector to the fuel rail. Male electrical connectors on the fuel rail are formed by exposing a portion of the electrical bus. The fuel delivery system includes an electrical connector assembly for connecting the male connector of the fuel injector to the male connector of the fuel rail. Thus, when the fuel injector is inserted into the fuel rail, mechanical orientation and retention is achieved while at the same time an electrical connection is made.
