Fuel Injector Removal:

4. Using a small pair of pliers, carefully lift at the center of the injector, and loosen the injector by rocking it back and forth. Do not twist the injector to free it, because it has a locating tab that fits into a slot in the throttle body bore. After the injector is removed discard both injector "O" rings and the old centering ring.

INSTALLATION

2. Install the centering ring on top of the upper "O" ring.
3. Position the locating tab on the bottom of the injector with the slot in the bottom of the housing and install the injector. Install the injector retainer and tighten the mounting screws securely.
4. Reconnect the injector wire, and install the lower and upper air inlet bonnets.
5. Reconnect the negative battery terminal.
