E3684M Fuel Pump Module for Chevrolet Silverado and GMC Sierra 1500

Extended cranking, intermittent no-start, low fuel pressure, hesitation under load, stalling, or an inaccurate fuel-gauge reading can involve the in-tank module. This BDFHYK E3684M electric fuel pump module assembly is an aftermarket replacement for specific 2004–2007 Chevrolet Silverado 1500 and GMC Sierra 1500 applications. Confirm the Classic designation, engine, cab, bed length, wheelbase, tank capacity, tank position, connector, sender layout, and OE number before installation.

Confirm E3684M Silverado and Sierra Fitment

2004–2006 Chevrolet Silverado 1500

2004–2006 Silverado 1500 with the 4.8L or 5.3L V8 engine in matching truck and tank configurations
2006 Silverado 1500 with the 6.0L V8 engine in matching configurations

2007 Chevrolet Silverado 1500 Classic

2007 Silverado 1500 Classic with the 4.8L, 5.3L, or 6.0L V8 engine where the cab, bed, wheelbase, and tank match E3684M

2004–2007 GMC Sierra 1500 and Sierra 1500 Classic

2004–2006 GMC Sierra 1500 with the 4.8L, 5.3L, or 6.0L V8 engine in matching configurations
2007 GMC Sierra 1500 Classic with the 4.8L, 5.3L, or 6.0L V8 engine in matching configurations

Some E3684M catalog references specify Crew Cab trucks with the 5.75-foot bed. Do not assume fitment for every cab, bed, wheelbase, or tank configuration sharing the same model and engine.

E3684M OE and Interchange Number Check

Listed Cross-Reference Numbers

E3684M, FG0494, MU1314, MU1422, M10095, 19133480, 19133481, 19152213, and 88965377.

Match the Module to the Exact Truck Tank

Compare cab and bed configuration, wheelbase, tank capacity and position, flange, connector, fuel-line fittings, module depth, reservoir, pickup, strainer, sender, float arm, seal, and lock-ring engagement with the removed assembly.

Check the Silverado or Sierra Fuel System First

Fuel Pressure and Electrical Diagnosis

Measure fuel pressure during key-on, cranking, idle, and load
Check available voltage and ground at the module connector under pump load
Inspect the relay, fuse, wiring, connector, fuel filter, lines, pressure-control components, and injectors
Test the sender and gauge circuit separately when the fuel-level reading is inaccurate

Inspect the Truck Fuel Tank

Rust, sediment, water, degraded fuel, or debris can restrict the strainer and damage the replacement pump. Clean the tank and correct the contamination source before installation.

Silverado and Sierra Installation Notes

Record Cab, Bed, Wheelbase, and Tank Data

Before removal, record the VIN, RPO information, cab style, bed length, wheelbase, tank capacity, and original module number. Relieve fuel pressure, disconnect the battery, support the vehicle and tank correctly, and clean the tank opening.

Prime, Leak-Test, and Confirm Gauge Operation

Compare the old and new modules, use the correct seal, and confirm full lock-ring engagement. After installation, prime the system, verify pressure, inspect the seal and fuel connections for leaks, confirm gauge operation, and recheck the electrical circuit.

Before Ordering the E3684M Fuel Pump Assembly

Silverado and Sierra Truck Checklist

Confirm Silverado 1500, Sierra 1500, or the 2007 Classic designation
Verify the exact model year and engine combination listed above
Confirm cab style, bed length, wheelbase, tank capacity, and tank position
Match E3684M or the applicable OE/interchange number
Compare connector, line fittings, module height, pickup, sender, and float arm
Confirm the seal, lock ring, and installation hardware shown with the product

This is a BDFHYK aftermarket replacement fuel pump module assembly, not a Chevrolet, GMC, or GM factory OEM component.

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: Does E3684M fit every 2004–2007 Silverado or Sierra 1500?

A: No. Model year, Classic designation, engine, cab, bed, wheelbase, tank capacity and position, connector, sender layout, and OE number must match.

Q: Which Chevrolet Silverado engines are listed?

A: The listed range includes 2004–2006 4.8L and 5.3L, 2006 6.0L, and 2007 Silverado 1500 Classic 4.8L, 5.3L, or 6.0L in matching configurations.

Q: Which GMC Sierra engines are listed?

A: The listed range includes 2004–2006 Sierra 1500 and 2007 Sierra 1500 Classic with 4.8L, 5.3L, or 6.0L engines in matching configurations.

Q: Why must cab and bed length be checked?

A: Some E3684M references specify Crew Cab trucks with a 5.75-foot bed. Different truck dimensions can use a different tank and module geometry.

Q: Can E3684M replace FG0494 or MU1314?

A: Those numbers are listed as cross-references, but the tank opening, connector, line fittings, module height, pickup, sender, and float arm must also match.

Q: Does E3684M fit flex-fuel trucks?

A: Do not infer fuel compatibility from the model or engine alone. Confirm the VIN, RPO data, original module, and fuel-system specification.

Q: Will replacing the module correct hesitation or stalling?

A: Only when testing confirms insufficient pump output, low pressure, or an internal module fault. Electrical, injector, ignition, air, and control faults can cause similar symptoms.

Q: Should pressure and voltage be tested first?

A: Yes. Test fuel pressure under the required operating conditions and check available voltage and ground at the module under load.

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

A: The module design includes a float-arm sender arrangement. Compare the sender circuit, connector, and float geometry with the removed assembly.

Q: What should be inspected in the truck fuel tank?

A: Inspect for rust, sediment, water, degraded fuel, debris, damaged baffles, and pickup restrictions before installation.

Q: What should be checked after installation?

A: Prime the system, verify fuel pressure, inspect the tank seal and connections for leaks, confirm gauge operation, and recheck the electrical circuit.
