NOTE: To release the fuel pressure in the high pressure fuel tube, wrap the high-pressure fuel pump flare nut with a shop towel to absorb any residual fuel pressure during the loosening of high-pressure fuel pump flare nut.NOTE: When only disconnecting the high pressure fuel tube at the high-pressure fuel pump flare nut, the high pressure fuel tube can be reused.
Remove the high pressure fuel tube bracket nut and discard. Disconnect the high-pressure fuel pump flare nut.
-
NOTE: Alternately loosen the high-pressure fuel pump bolts one complete revolution at a time.
Remove the high-pressure fuel pump bolts and discard. Remove the high-pressure fuel pump.
- Remove the high-pressure fuel pump O-ring seal and discard.
- Remove the high-pressure fuel pump roller tappet.
- Inspect the high-pressure fuel pump roller tappet. If any flat spots or scoring are found, especially in the indicated areas, then inspect the high-pressure fuel pump and the high-pressure fuel pump roller tappet drive lobe. Install new components as necessary.
