Module Functions	Picks up fuel from the rear steel tank, supports in-tank pumping in the original dual-pump system, and measures fuel level
Fuel Type	Gasoline
Fitment Verification	Confirm VIN, model, year, engine, rear tank position, steel tank material, dual-pump system, flange, connector, lines, float arm, and OE number
Included Components	Rear-tank hanger/pump and sender assembly with strainer, float arm, and connections as pictured
Installation Position	Rear steel fuel tank
Fitment Priority	Rear tank position, steel tank, and dual-pump system take priority over F-Series model or engine name
Symptoms to Check	No start on selected tank; low pressure; stalling; weak acceleration; tank-switching fault; inaccurate fuel gauge
Related Parts to Check	Frame-mounted in-line high-pressure pump; tank selector valve; switch; relay; wiring; ground; connector; front-tank module; fuel lines
Installation Note	Relieve pressure, disconnect the battery, identify the rear steel tank, inspect the in-line pump and selector system, replace the seal, and verify leaks, pressure, tank switching, and gauge operation
Part Classification	OE-style aftermarket rear-tank fuel pump hanger and sender
Replacement Part Note	The original system can use both an in-tank pump and a frame-mounted in-line pump; test both before replacement

A no-start condition on the rear tank, low fuel pressure, stalling, weak acceleration, failed tank switching, or an inaccurate fuel gauge can result from a rear-tank assembly fault after the selector valve, wiring, and frame-mounted pump are tested. The BDFHYK E2104S is an OE-style hanger, pump, and sender for specified 1987–1989 Ford F-Series trucks with a rear steel tank. Confirm tank position, tank material, dual-pump layout, flange, connector, lines, float arm, and OE number before installation.

E2104S Rear Steel-Tank Fitment for Ford F-Series

Specified 1987–1989 Ford F-150 rear steel-tank applications
Specified 1987–1989 Ford F-250 rear steel-tank applications
Specified 1987–1989 Ford F-350 rear steel-tank applications
Specified Ford F-Super Duty rear steel-tank applications
4.9L, 5.0L, 5.8L, or 7.5L gasoline engines as specified

Fitment must be confirmed from the VIN, fuel-tank configuration, removed module, and OE/interchange number. Similar vehicles can use different flanges, connectors, fuel-line arrangements, module depths, or sender layouts.

What the E2104S Assembly Does

Picks up fuel from the rear steel tank, supports in-tank pumping in the original dual-pump system, and measures fuel level. This is an OE-style aftermarket replacement intended to restore the original tank-side function when the application and physical module match.

Fitment Verification Before Installation

Rear fuel-tank position
Steel tank construction
Original dual-pump fuel-system layout
Flange, connector, and fuel-line arrangement
Float arm and sender configuration
E2104S or listed Ford/interchange number

Diagnosis Before Replacing the Fuel Module

Test the frame-mounted in-line high-pressure pump.
Check tank selector valve, switch, relay, wiring, ground, and voltage drop.
Measure pressure while operating the rear tank.
Compare rear- and front-tank sender readings and inspect tank contamination.

A failed fuel pump module should be confirmed with pressure, voltage, ground, and circuit testing. Do not replace the module solely because the engine does not start or the fuel gauge is inaccurate.

Installation and Post-Installation Checks

Relieve pressure, disconnect the battery, identify the rear steel tank, inspect the in-line pump and selector system, replace the seal, and verify leaks, pressure, tank switching, and gauge operation. Do not energize an electric fuel pump outside fuel. Follow the vehicle service procedure for tank removal, sealing, and pressure testing.

Application Summary

The original system can use both an in-tank pump and a frame-mounted in-line pump; test both before replacement. Compare all pictured components and listed references with the removed assembly before ordering or installation.

What’s Included in This Fuel Pump Assembly

Complete fuel pump module
Integrated fuel level sending unit
Fuel strainer (filter sock)
Housing and mounting components

This fuel pump assembly is designed as a direct replacement unit that restores proper fuel delivery and fuel level monitoring.

Estimated Installation Time

Professional mechanic: 1–2 hours
DIY installation: 2–4 hours

Fuel pump replacement usually requires accessing the fuel tank or service panel depending on the vehicle design. Always disconnect the battery and relieve fuel system pressure before installation.

Pump Only vs Fuel Pump Assembly

Option	Description
Replace Pump Only	Lower parts cost but requires disassembling the existing module and reusing older components.
Replace Complete Assembly	A complete module designed for direct installation, helping restore reliable fuel delivery more efficiently.

Most modern vehicles use integrated fuel pump modules, which makes replacing the full assembly the more reliable solution.

Q: What type of part is E2104S?

A: It is a rear steel-tank fuel pump hanger and sender assembly for specified 1987–1989 Ford F-Series trucks.

Q: Which tank position is required?

A: The verified E2104S application uses the rear fuel tank.

Q: Which tank material is required?

A: Referenced E2104S applications use a steel rear tank.

Q: Does the truck use another fuel pump?

A: Many original systems use an in-tank low-pressure pump plus a frame-mounted in-line high-pressure pump. Both must be tested.

Q: Which trucks are associated with E2104S?

A: Specified F-150, F-250, F-350, and F-Super Duty gasoline applications are associated with it.

Q: Which OE references should be compared?

Q: Can a selector valve fault cause similar symptoms?

A: Yes. Test the tank selector valve, switch, wiring, and both tank circuits before replacing the rear unit.

Q: Does the assembly include a fuel-level sender?

A: Yes. The pictured configuration includes a float-arm sender.

Q: Can the pump be operated dry?

A: No. Do not energize the electric pump outside fuel.

Q: What must be checked after installation?

A: Inspect for leaks and verify pressure, rear-tank operation, tank switching, and fuel-gauge response.
