A failing fuel pump module on your 2005 Mustang 4.0L or 4.6L can mean hard starts, fuel starvation at high RPM, or a gauge that reads empty when the tank is not. All Classic Parts delivers a direct-fit replacement assembly that restores correct fuel delivery and accurate level readings without any splicing or fabrication.
Complete assembly, ready to install. The module arrives as a full unit with OE-matched wiring connectors that plug straight into the factory harness. No wiring modifications, no adapter pigtails, no guesswork on pin assignments.
Built-in float arm restores the fuel gauge. The integrated float arm sends the same electrical signal as the factory unit, so the gauge reads accurately from full to empty the moment the assembly drops in. Replacing just the pump and leaving a worn float arm behind is a common mistake this complete assembly prevents.
Direct replacement for OEM fitment. Engineered as a drop-in substitute for OEM part 4R3Z-9H307-AA, the assembly matches the factory dimensions, sender calibration, and connector layout for a clean installation with no trimming or bracket modification.
