ABSTRACT:
A fuel rail including an electrical strip is utilized to electrically couple fuel injectors to an external electrical connector situated on an outside surface of the fuel rail. The fuel rail is preferably made from plastic and includes injector cups situated in fuel injector attachments for mechanically receiving the fuel injectors. The fuel injectors are electrically and mechanically coupled to the fuel rail by an upward mechanical motion. The fuel injectors include clip-like electrical connectors which receive connector fingers of the electrical strip which are disposed in the injector cups. The fuel rail was preferably molded in a manifold.
