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: Which vehicles use the E3706M module?

A: It covers selected 2005–2007 Chevrolet Avalanche, Suburban 1500 and GMC Yukon XL 1500 5.3L flex-fuel applications.

Q: Is this a gasoline-only module?

A: No. The verified E3706M application group is associated with 5.3L flex-fuel vehicles.

Q: Does it fit Tahoe or standard-wheelbase Yukon models?

A: Not automatically. This module family is associated with Avalanche, Suburban 1500 and Yukon XL 1500 applications.

Q: Is the fuel-level sending unit included?

A: Package configuration must be checked. Some OE/service equivalents are listed without the fuel-level sensor.

Q: Why must the original module be compared?

A: Sender package, pressure sensor, connectors, fuel ports, flange and module height can differ.

Q: Which OE numbers should be checked?

A: Compare 19133544 or 19208963 and verify the module by VIN.

Q: Which interchange numbers are commonly listed?

A: E3706M, FG0809, SP6603M and MU1474 are common references.

Q: What should be tested before replacement?

A: Test fuel pressure, pump voltage and ground under load, fuse and relay operation, wiring, fuel-line restriction, and sender continuity before replacing the module.

Q: Can a non-flex-fuel module be substituted?

A: No. Fuel-system calibration, pump/module configuration and line layout can differ.

Q: What checks are required after installation?

A: Prime the system, inspect the flange and fuel connections for leaks, measure fuel pressure, and confirm normal fuel-gauge operation.
