•  Use of a deformed injector clip will cause the fuel injector to be connected incorrectly and could result in fuel leakage. Make sure to replace with a new injector clip after removing it.

1.  Detach one side of the injector clip from the injector port flange.

Fuel Injector Installation Note

1.  Apply a small amount of clean oil to a new O-ring.

Caution
•  A damaged O-ring could cause fuel leakage. Be careful not to damage the O-ring when installing the fuel injector.
•  If there is foreign material on the fuel injector connecting part, it might damage the fuel injector and fuel distributor. To prevent this, clean the connecting part before connecting the fuel injector.

2.  Install the fuel injector straight to the injector port.
