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.
A device to suction fuel from a fuel injector and a device to attach a fuel return line to a fuel injector with a C-shaped main body partially encircling the fuel injector having two retaining arms which abut the fuel injector and grip it from the back at least to a small degree, with a connector coacting with a drain passage of the fuel injector and at least one connecting fitting for the fuel return line. The connecting fitting and the connector are fluidically connected. The free ends of the retaining arms have a first section in which they are angled towards each other and towards the base of the main body.
A support element for the mutual support of a fuel injector in a valve seat, in particular of the valve seat of a cylinder head of an internal combustion engine, and of the fuel injector at a fuel distribution line has a clasp and thereon developed radially and axially deformable clips.
A fuel delivery system in accordance with the present invention comprises a fuel rail having an outlet opening and an outlet cup that is insertable into the outlet opening. The cup includes a flange. The flange includes at least one tab extending therefrom. The cup further defines a vertical axis extending therethrough. The system further includes a fuel injector with an inlet insertable within the cup. The system still further includes a retention clip. The clip includes an inner peripheral surface, at least a portion of which is configured for engagement with the injector when the clip and injector are assembled together. The clip further includes at least one arm, the arm further including a finger configured for spring engagement with the tab of the cup. The clip is operative to limit the movement of the fuel injector when it is assembled with the clip and inserted in the cup.

A fuel delivery system comprising a fuel rail having an outlet and a receptor cup associated therewith. The system further including a fuel injector having an inlet, an outlet and a body therebetween. The inlet is configured for insertion into the cup of the fuel rail and for fluid communication with the outlet thereof. The system still further including a retention clip configured for engagement with the fuel injector and the cup in order to couple the fuel injector with the fuel rail. In the inventive system, the fuel injector further includes a load distribution feature. This feature is configured to engage a portion of the retention clip and to assist with the distribution about the clip of a load applied to the injector.
