Fuel Injector: Installation
- If replacing injector, always replace it with an identical part. Lubricate new upper and lower "O" rings with automatic transmission fluid and place them on injector. Ensure upper "O" ring lies in groove and lower "O" ring is flush against filter. Install fuel injector into throttle body.
- Ensure fuel injector connector end faces cutout in throttle body for wiring grommet. Install retainer. Coat retaining screw threads with locking compound. Tighten retaining screw to 27 INCH lbs. (3 N.m). With engine off and ignition on, check for fuel leaks.
