Abstract
An anti-rotation clip for joining a fuel injector body to a fuel rail socket. A C-shaped base is formed to slide into an annular groove in the injector body. A pair of tangs extend from the base to straddle a rib on the injector body to prevent rotation between the clip and the injector. Opposed sidewalls extending from the base include windows for receiving a radial flange of the fuel rail socket to correctly position the fuel injector axially within the socket. Each window is divided by a locking bar for reception in a notch in the socket flange to prevent rotation between the clip and the socket. The radial positions of the injector rib and flange notch are selected such that the injector will be properly oriented with respect to the engine after installation therein.
