E3688M Fuel Pump Module for Chevrolet Colorado, GMC Canyon, and Isuzu i-Series

Extended cranking, intermittent no-start, low or unstable fuel pressure, hesitation under load, stalling, abnormal pump operation, or an inaccurate fuel-gauge reading can involve the in-tank module. This BDFHYK E3688M electric fuel pump module assembly is an aftermarket replacement for specific 2006–2008 Chevrolet Colorado, GMC Canyon, and Isuzu i-Series gasoline applications. Confirm the exact year, engine, cab and bed configuration, tank design, pressure-sensor arrangement, connector, module height, sender layout, and OE number before installation.

Confirm E3688M Vehicle and Engine Fitment

Chevrolet Colorado and GMC Canyon

2006 models with the 2.8L L4 or 3.5L L5 engine
2007–2008 models with the 2.9L L4 or 3.7L L5 engine

Isuzu i-Series

2006 Isuzu i-280 with the 2.8L L4 engine
2007–2008 Isuzu i-290 with the 2.9L L4 engine
2006 Isuzu i-350 with the 3.5L L5 engine
2007–2008 Isuzu i-370 with the 3.7L L5 engine

The model name alone does not confirm the fuel tank and module configuration. Compare the original assembly and use VIN-based application data before installation.

Listed Cross-Reference Numbers

E3688M, P76237M, F2699A, SP6435, SP6435M, FG0435, 530-2540, 67545, MU1611, M10097, 19122012, 19133531, 19167115, 19331941, 323-00141, and 8191671150.

Compare the Pressure Sensor and Module Geometry

Reference configurations for this module commonly include a fuel-tank pressure sensor, but the supplied part must still match the original sensor connector and mounting arrangement. Compare the flange, electrical connector, line fittings, reservoir, overall height, pickup, strainer, sender, float arm, seal, and lock-ring engagement.

Check the Fuel System Before Replacing E3688M

Measure fuel pressure during key-on, cranking, idle, and load
Check available voltage and ground at the module under pump load
Inspect the relay, fuse, wiring, connector terminals, filter, lines, and injectors
Test the sender, gauge circuit, and tank-pressure circuit separately when related faults are present

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.

E3688M Installation Notes

Relieve fuel pressure, disconnect the battery, support and clean the tank, and compare the old and new modules before installation. Use the correct seal and confirm full lock-ring engagement. After installation, prime the system, verify fuel pressure, inspect the tank seal and fuel connections for leaks, confirm gauge operation, and scan the tank-pressure circuit where applicable.

Before Ordering the E3688M Fuel Pump Assembly

Confirm the exact year, model, and 2.8L, 2.9L, 3.5L, or 3.7L engine combination
Verify cab, bed, wheelbase, tank, and emissions configuration
Match E3688M or the applicable OE/interchange number
Compare the connector, line fittings, pressure sensor, module height, sender, and float arm
Confirm the seal, lock ring, and installation parts shown with the product

This is a BDFHYK aftermarket replacement fuel pump module assembly, not a Chevrolet, GMC, Isuzu, 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 E3688M fit every 2006–2008 Colorado or Canyon?

A: No. The exact year, engine, cab, bed, tank design, connector, module height, pressure-sensor arrangement, sender layout, and OE number must match.

Q: Which engines are listed for 2006 Colorado and Canyon models?

A: The listed 2006 applications use the 2.8L L4 or 3.5L L5 engine.

Q: Which engines are listed for 2007–2008 Colorado and Canyon models?

A: The listed 2007–2008 applications use the 2.9L L4 or 3.7L L5 engine.

Q: Which Isuzu i-Series models are listed?

A: The listed range includes the 2006 i-280 and i-350 plus the 2007–2008 i-290 and i-370, with the corresponding engine shown in the description.

Q: Can E3688M replace P76237M or FG0435?

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

Q: Is a fuel-tank pressure sensor included?

A: Reference configurations commonly include a pressure sensor. Confirm the supplied assembly, sensor connector, and mounting arrangement against the original module before installation.

Q: Will replacing E3688M correct a no-start condition?

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

Q: Should fuel pressure and voltage be tested first?

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

Q: What should be inspected inside the 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 seal and connections for leaks, confirm gauge operation, and scan the tank-pressure circuit where applicable.
