Ford F-150 Lincoln Mark LT Fuel Pump Module Assembly 2004-2008 4.2L 4.6L 5.4L Replacement E2441M 4L3Z-9H307-CF BDFHYK

Extended cranking, low measured fuel pressure, hesitation under load, intermittent stalling, or an inaccurate fuel gauge can indicate an in-tank module fault after the fuse, relay, power supply, ground, wiring, and fuel lines have been tested. This E2441M replacement module is intended for specified 2004–2008 Ford F-150 and 2007–2008 Lincoln Mark LT gasoline trucks equipped with the approximately 35.7-gallon extended-range single tank. Confirm the engine, VIN, wheelbase, tank capacity, OE number, four-terminal connector, fuel outlet, flange, module height, and float-arm layout before ordering.

Fuel Pump Module Fitment for Extended-Range F-150 and Mark LT Tanks

Verified coverage includes selected F-150 4.2L V6, 4.6L V8, and 5.4L V8 applications and selected Mark LT 5.4L V8 applications. Wheelbase, VIN, engine, and tank specifications vary across model years. A standard-capacity or different single-tank module is not interchangeable solely because the mounting flange looks similar.

Fitment Verification

• Confirm the approximately 35.7-gallon extended-range single tank.
• Verify the engine, VIN, and wheelbase; applicable configurations include approximately 144.5, 144.7, 150.5, and 163.3 inches depending on year.
• Match E2441M, 4L3Z-9H307-CF, SP2005M, FG0850, P76344M, or another verified interchange.
• Compare the oval four-terminal connector, 3/8-inch quick-connect outlet, flange, reservoir, module height, and float arm.

Module Functions and Service Components

• Electric in-tank pump supplies fuel to the engine-side delivery system.
• Fuel-level sender, float arm, and reservoir support pickup and gauge reporting.
• The quick-connect outlet and electrical connector must match the original module.
• Confirm seal, lock-ring, and service-hardware contents before installation and use a compatible new tank seal.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test voltage and ground under load, inspect the fuse and relay, and check the outlet, connector, and sender circuit. An incorrect tank-size module, restricted line, damaged wiring, tank contamination, or an engine-management fault can create similar symptoms.

Installation Notes

Relieve fuel-system pressure, disconnect the battery, and support the extended-range tank safely. Clean the tank and sealing surface, install the correct new seal, protect the float arm, and secure the module evenly. Prime the system, inspect the flange and outlet for leaks, measure fuel pressure, and confirm normal gauge operation.
