High-Pressure Fuel Pump: Removal
NOTE:
Do not loosen any fittings or plugs on the high-pressure fuel pump.
- 2.
Release the fuel system pressure. Refer to: Fuel System Pressure Release .
- 3.
Disconnect the battery. Refer to: Battery Disconnect and Connect .
- 5.NOTE: When removing or installing the high-pressure fuel pump noise insulator, spreading the openings will reduce the risk of damage.
Remove the high-pressure fuel pump noise insulator.
- 6.
Disconnect the high-pressure fuel pump fuel supply hose. Refer to: Quick Release Coupling .
- 8.
Remove the high-pressure fuel pump drive unit noise insulator retainer, remove the brake vacuum pump noise insulator retainer and remove the wire harness retainer. Remove the high-pressure fuel pump drive unit noise insulator and remove the brake vacuum pump noise insulator.
- 9.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.
- 1.
Remove the high-pressure fuel tube nut.
- 2.
Remove the high-pressure fuel tube bolt.
- 3.
Disconnect the high-pressure fuel tube flare nuts.
- 4.
Remove and discard the high-pressure fuel tube.
- 1.
- 10.
Remove the high-pressure fuel pump bracket bolts and then remove the high-pressure fuel pump bracket.
- 11.NOTE: Alternately loosen the high-pressure fuel pump bolts one complete revolution at a time.
Remove and discard the high-pressure fuel pump bolts and then remove the high-pressure fuel pump.
- 14.
Inspect the high-pressure fuel pump 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 tappet drive lobe. Install new components as necessary.
