Fuel Injector: Service and Repair

CAUTION: Reduce fuel pressure before removal.

REMOVAL SERVICE POINT
Remove the fuel rail (with the injectors attached to it).

CAUTION: Care must be taken, when removing the fuel rail, not to drop the injectors.


INSTALLATION SERVICE POINTS



1. Apply a small amount of clean engine oil to the 0-ring.

CAUTION: Do not let the engine oil get into the fuel rail.

2. While turning the injector to the left and right, install it to the fuel rail.
3. Check to be sure that the injector turns smoothly. If it does not turn smoothly, the 0-ring may be trapped, remove the injector and then re-insert it into the fuel rail and check once again.
