CLEANING AND INSPECTION
Inspect fuel injectors for damage; replace if necessary.
INSTALLATION
IMPORTANT: When replacing injectors, be certain to replace with the identical part
and part number. Other injectors may have the same appearance, yet have a different
part number and be calibrated for a different flow rate, and if installed, would cause
performance difficulty or damage to the ECM.
1. Lubricate the o-ring with a water/soap solution. Insert the fuel injector in the fuel rail.
