## Abstract

A fuel injector with an anti-rotation clip for use in conjunction with a twist lock fuel injector inserted into a receiving fuel cup. The clip includes at least one connector leg which extends at least partially over the electrical connector for the fuel injector and locks the clip against rotation relative to the fuel injector electrical connector. A protrusion on a fuel cup arm engages a notch formed in the fuel cup to lock the arm against rotation relative to the fuel cup.

## Claims

### Claim 1

A fuel injector assembly comprising:
a fuel injector having an outwardly extending electrical connector;
a fuel cup in which said fuel injector is twisted into and having a notch;
a clip for locking the fuel injector against rotation relative to the fuel cup comprising:
at least one connector leg which extends at least partially around a first side of the electrical connector and locks said clip against rotation relative to the electrical connector,
a fuel cup arm having a portion which engages the notch and locks said clip against rotation relative to the fuel cup.
