ABSTRACT:
A fuel system for a direct injection internal combustion engine having a fuel rail and at least one annular cup secured to the fuel rail so that fuel from the fuel rail flows into the cup. A direct injection fuel injector has a portion axially insertable into the fuel cup to a connected position. A recessed channel on the fuel injector registers with a slot in the annular cup when in the connected position so that a U-shaped clip insertable into the cup slots and the fuel injector channels secures the fuel injector and cup together against axial movement.
