Common Problems This Part Can Address

• Hard starting caused by weak or failing fuel delivery
• Engine stalling from inconsistent in-tank pump output
• Incorrect fuel gauge readings from a worn sender assembly
• Fuel pressure loss in gasoline fuel systems
• Poor drivability related to restricted pump or strainer performance

Installation Notes and Tips

Before installation, clean the fuel tank to help prevent seal contamination and future sealing issues, as noted for the listed Ford Fusion and Mercury Milan applications. Verify electrical connector style, outlet connection, and system pressure requirements before service. Because this is an in-tank module assembly, proper tank access and fuel system depressurization are required during replacement.
