A failing fuel pump module on your 1999-2000 Mustang 3.8L or 4.6L can mean hard starts, stalling, or a fuel gauge that reads incorrectly. All Classic Parts delivers a direct-fit replacement assembly that restores proper fuel delivery and accurate tank readings without improvised adapters or modified wiring.
Complete drop-in replacement. The assembly replaces the entire OEM unit, including the pump, housing, and all associated hardware, so there are no partial kits to piece together. It fits the factory mounting location exactly, matching OEM part number XR3Z-9H307-AD.
OE wiring connectors included. The harness connectors match the factory plugs directly, eliminating the need to splice, crimp, or adapt any wiring. Plug in and the electrical connection is solid from the first start.
Integrated float arm restores gauge accuracy. The built-in float arm sends the same electrical signal as the original unit, so the fuel level gauge reads correctly on the instrument cluster without any additional calibration or sender work.
