Fuel Pump Module Assembly E2443M For 2005-2006 Expedition/Lincoln Navigator V8 5.4L 2005 2006 Engine 5.4L/V8

Extended cranking, low measured fuel pressure, hesitation, 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 E2443M replacement module is intended for specified 2005–2006 Ford Expedition and Lincoln Navigator models with the 5.4L V8 gasoline engine. Confirm the model, year, engine, OE number, white rectangular four-terminal connector, 3/8-inch quick-connect outlet, flange, module height, and float-arm geometry before ordering.

Fuel Pump Module Fitment for Expedition and Navigator

Verified coverage includes selected 2005–2006 Ford Expedition and Lincoln Navigator 5.4L gasoline configurations. A module with a different electrical connector, outlet, tank-pressure-sensor arrangement, flange, or sender calibration is not interchangeable solely because the vehicle name and year match.

Fitment Verification

• Confirm a 2005–2006 Expedition or Navigator with the 5.4L V8 gasoline engine.
• Match E2443M, 5L1Z-9H307-AA, 6L1Z-9H307-A, FG0877, P76133M, or SP2101M.
• Compare the white rectangular male connector with four blade terminals.
• Verify the single 3/8-inch quick-connect outlet, flange, reservoir, module height, and float arm.

Module Functions and Included Components

• Electric in-tank pump supplies fuel to the engine-side delivery system.
• Fuel-level sender, float arm, reservoir, and inlet strainer support pickup and gauge reporting.
• A tank gasket is included in the verified configuration.
• The verified configuration is listed without a tank-pressure sensor, lock ring, wire harness, or integrated pressure regulator.

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 connector, outlet, sender circuit, and separate tank-pressure components. A restricted line, damaged wiring, tank contamination, sender fault, or engine-management issue can create similar symptoms.

Installation Notes

Relieve fuel-system pressure and disconnect the battery before opening the tank. Clean the tank and sealing surface, install the supplied compatible gasket, obtain the correct lock ring or service hardware when required, and keep the float arm clear. Prime the system, inspect the flange and outlet for leaks, measure fuel pressure, and confirm normal gauge operation.
