E2237S Fuel Pump Module Assembly for Ford F-150 1999-2003 4.2L 4.6L 5.4L Replace F85Z-9H307-BA

E2237S Fuel Pump Module Assembly for Ford F-150, F-150 Heritage, and F-250

Long cranking, a no-start condition, pressure loss under load, hesitation, stalling, or an inaccurate fuel-gauge reading can involve the in-tank fuel pump module, but electrical and pressure testing should be completed before replacement. This BDFHYK E2237S module is an aftermarket replacement for the specified Ford truck applications. Confirm the year, engine, cab and bed configuration, fuel-tank size and location, connector, flange, line fittings, sender layout, and OE number before ordering.

Compare the cross-reference with the removed module and tank. Verify the tank capacity and position, module flange, electrical connector, fuel-line fittings, overall height, pickup orientation, and fuel-level sender geometry.

What the E2237S F-150 Fuel Pump Module Controls

In-Tank Fuel Supply and Gauge Sender

The assembly places the electric pump, pickup, hanger, and fuel-level sender within the fuel tank. Correct module selection matters because pump position, pickup reach, and float-arm travel must match the specific truck tank.

Ford F-150 Symptoms to Diagnose Before Replacement

• Extended cranking or intermittent no-start
• Low fuel pressure or pressure loss during acceleration or towing load
• Hesitation, stalling, or reduced engine power
• Fuel gauge stuck, inaccurate, or unstable
• No pump operation caused by a relay, fuse, wiring, ground, connector, or control issue

Inspect the fuel filter, relay, fuse, wiring, ground, tank contamination, lines, regulator or pressure-control system, injectors, and control command before condemning the complete module.

Ford F-150 Fuel Tank Installation Notes

Safely Lower or Access the Truck Fuel Tank

Relieve fuel pressure, disconnect the battery, support the vehicle securely, and use equipment suitable for the size and weight of the truck tank. Work in a ventilated area away from heat, sparks, and flame. Clean the top of the tank before opening it.

Verify the E2237S Module Before Locking It Into Place

Compare the new and removed assemblies. Confirm flange and lock-ring fit, connector indexing, fuel-line sizes, module height, pickup position, float-arm sweep, and seal placement. The sender float must move through its range without contacting the tank wall or baffle.
