Electric Fuel Pump Replacement For Ford uFsion L4 2.5L, Lincoln MKZ L4 2.5L

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 E2561M replacement module is intended for specified Ford Fusion, Lincoln MKZ, and Mercury Milan 2.5L applications. Confirm the exact model year, gasoline or gasoline-electric hybrid configuration, VIN, OE number, four-terminal connector, single quick-connect outlet, flange, module height, and float-arm layout before ordering.

E2561M Fitment for Fusion, MKZ, and Milan 2.5L

Verified coverage includes specified 2010–2012 Ford Fusion 2.5L vehicles, 2010–2011 Mercury Milan 2.5L vehicles, and 2011–2012 Lincoln MKZ 2.5L vehicles. Catalog-listed gasoline and hybrid configurations can use different control strategies, so the VIN, trim, and original module must be checked.

Fitment Verification

• Confirm the exact model, year, 2.5L engine, and gasoline or hybrid powertrain.
• Match E2561M, FG1141, SP2097M, P76583M, or Ford AE5Z-9H307-A/F.
• Compare the four-terminal connector, single 3/8-inch quick-connect outlet, flange, module height, reservoir, and float arm.
• Do not substitute a module for a different engine, tank, connector, outlet, sender range, or pressure-sensor configuration.

Module Functions and Included Components

• Electric in-tank pump supplies low-pressure fuel to the engine-side delivery system.
• Integrated regulator, reservoir, and inlet strainer support pickup and pressure control.
• Fuel-level sender and float arm provide tank-level information.
• The verified FG1141 configuration does not include a fuel-tank pressure sensor.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test pump voltage and ground under load, inspect the fuse and relay, and check the connector for corrosion or heat damage. On hybrid applications, follow the vehicle-specific high-voltage shutdown procedure before service. Restricted lines, tank contamination, sender faults, or engine-control problems can create similar symptoms.

Installation Notes

Relieve fuel-system pressure, disconnect the 12-volt battery, and follow the correct hybrid isolation procedure where applicable. Clean the tank and sealing surface, install a new compatible seal, keep the float arm clear, and secure the module evenly. Prime the system, inspect for leaks, measure fuel pressure, and confirm normal gauge operation.
