Installation Instructions
- Confirm the vehicle year, model, fuel-pump module, connector layout, and FORD-FPHWK-HD package label before installation.
- Relieve fuel-system pressure, disconnect the battery, and follow the current DeatschWerks technical sheet and vehicle service procedures.
- Route the battery feed, grounds, relays, fuses, module leads, and pressure-switch wiring away from heat, abrasion, sharp edges, and moving parts.
- Make every plug-and-play connection fully and secure the harness so steering, suspension, exhaust, and driveline movement cannot contact it.
- Set the adjustable pressure switch only according to the fuel-system design and current DeatschWerks instructions.
- Reconnect power, prime the system, and check voltage, current draw, pump staging, fuel pressure, leaks, and diagnostic faults.
- Verify the completed fuel system under controlled load and comply with all competition-use and local legal requirements.
