High-Pressure Fuel Pump: Removal

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Do not work on the fuel system until the pressure has been released and the engine has cooled. Fuel in the high-pressure fuel system is hot and under very high pressure. High-pressure fuel may cause cuts and contact with hot fuel may cause burns. Failure to follow these instructions may result in serious personal injury.

WARNING: Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.

NOTE: Do not loosen any fittings or plugs on the high-pressure fuel pump.

NOTE: During the removal or installation of components, cap, tape or otherwise appropriately protect all openings and tubes/fittings to prevent the ingress of dirt or other contamination. Remove caps, tape and other protective materials prior to installation.

For exploded views, see fuel charging and controls - description and operation. Refer to: Fuel Charging and Controls - Component Location .
NOTE: Use care when removing the high-pressure fuel pump noise insulator. Spreading the openings will aid in removing the high-pressure fuel pump noise insulator and reduce the risk of damage.

Remove the high-pressure fuel pump noise insulator shield.
Release the fuel system pressure. Refer to: Fuel System Pressure Release .
Disconnect the battery. Refer to: Battery Disconnect and Connect .
Remove the air cleaner outlet pipe. Refer to: Air Cleaner Outlet Pipe .
Disconnect the high-pressure fuel pump electrical connector.
Disconnect the fuel jumper tube-to-high-pressure fuel pump quick connect coupling. Refer to: Quick Release Coupling .
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.

Remove the following items:
1. Remove the high pressure fuel tube bracket bolts.
2. Loosen the high pressure fuel tube-to-fuel rail flare nut.
3. Loosen the high pressure fuel tube-to-high-pressure fuel pump flare nut.
4. Remove and discard the high pressure fuel tube.
Alternately loosen the 2 high-pressure fuel pump bolts one complete revolution at a time.
Remove and discard the 2 high-pressure fuel pump bolts.
Remove the high-pressure fuel pump.
Remove and discard the high-pressure fuel pump O-ring seal.
