Restore reliable fuel delivery to your 2001-2004 Mustang with this direct-fit replacement fuel pump module assembly from All Classic Parts. When an aging or failing in-tank pump starves the engine of fuel, the symptoms range from hard starts and hesitation to a no-start condition. Swapping in a complete module assembly addresses the root cause cleanly, without piecing together individual components.
Drop-in fitment with no modifications. The assembly matches OEM geometry and mounting dimensions for the 2001-2004 Mustang application, so it seats into the factory tank opening without cutting, adapting, or re-routing any hardware. OE-style wiring connectors plug straight into the existing harness, eliminating the guesswork and improvised splicing that comes with universal units.
Complete assembly means fewer return trips to the parts store. Everything needed to restore proper fuel supply arrives as a single unit. The built-in float arm works exactly as the factory unit does, sending an accurate electrical signal to the fuel gauge so the sender reads correctly from day one.
A known OEM reference for verified fitment. This assembly corresponds to OEM part numbers 1R3Z-9H307-AA and 1R3Z-9H307-AB, giving installers a direct cross-reference to confirm compatibility before the tank comes down.
