Installation Note	Clean the tank, replace the seal and connect every fuel and vapor port correctly
Diagnostic Note	Test pressure, voltage, ground, relay, wiring, fuel lines and EVAP system

Extended cranking, low measured fuel pressure, hesitation under load, intermittent stalling, or an inaccurate fuel gauge can indicate an in-tank module fault after the fuse, relay, power supply, ground, wiring, and fuel lines have been tested. This E3797M replacement module is intended for specified 2008–2013 GM full-size SUV and utility-truck flex-fuel applications. Confirm the exact model, model year, engine, E85 or flex-fuel designation, tank configuration, OE number, flange, connector, fuel ports, module height, and float-arm layout before ordering.

E3797M Flex-Fuel Application Coverage

Verified coverage includes specified Cadillac Escalade ESV and EXT 6.2L, Chevrolet Avalanche and Suburban 1500 5.3L, and GMC Yukon XL 1500 5.3L or 6.2L flex-fuel configurations from the applicable 2008–2013 model range. Gasoline-only vehicles and modules for another fuel tank are not automatically interchangeable.

Fitment Verification

Confirm the vehicle is equipped with the catalog-listed flex-fuel or E85-capable system.
Match E3797M, FG1055, P76699M, P76292M, or the verified GM OE number.
Compare the tank flange, electrical connector, fuel-port count and orientation, full module height, reservoir, and float arm.
Verify the tank capacity, body style, drivetrain, and pressure-sensor or vapor-line provision before installation.

Module Functions and Included Components

Electric in-tank pump supplies fuel to the engine-side delivery system.
Integrated reservoir and inlet strainer support pickup during normal vehicle movement.
Fuel-level sender and float arm provide tank-level information.
Fuel-port, connector, and sensor provisions are vehicle- and tank-specific and must match the original module.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test voltage and ground at the connector under load, inspect the fuse and relay, and check the fuel lines and flex-fuel system information. Tank contamination, an incorrect tank module, sender faults, EVAP faults, restricted lines, or engine-management problems can create similar symptoms.

Installation Notes

Relieve fuel-system pressure and disconnect the battery before opening the tank. Clean the tank and sealing surface, install a new compatible seal, align every fuel and vapor connection, and keep the float arm clear. Secure the module evenly, prime the system, inspect for leaks, measure fuel pressure, and confirm normal gauge operation.

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: Which vehicles use the E3797M module?

A: It covers specified 2008–2013 Cadillac Escalade ESV or EXT, Chevrolet Avalanche or Suburban 1500, and GMC Yukon XL 1500 flex-fuel configurations.

Q: Does E3797M fit gasoline-only vehicles?

A: Do not assume compatibility. This module family is associated with flex-fuel or E85-capable applications and must match the VIN and OE number.

Q: Which engines are covered?

A: Coverage includes selected 5.3L and 6.2L V8 flex-fuel configurations, depending on the exact model and year.

Q: Can fitment be confirmed by model year and engine alone?

A: No. Confirm flex-fuel status, tank capacity and layout, OE number, flange, connector, ports, module height, and sender geometry.

Q: Is the fuel-level sender included?

A: Yes. The complete module includes the sender and float arm.

Q: Is the fuel-tank pressure sensor included?

A: Sensor provision can vary by tank and interchange. Compare the original module and product images before installation.

Q: Why does the fuel tank configuration matter?

A: Similar GM models can use different module heights, flanges, ports, sender ranges, and vapor connections for different tanks.

Q: What symptoms can indicate module failure?

A: Low measured pressure, long cranking, hesitation, stalling, and incorrect gauge readings can indicate a fault after circuit checks.

Q: What should be tested before replacement?

A: Test voltage and ground under load, fuse and relay operation, pressure, wiring, lines, sender circuit, tank condition, and EVAP connections.

Q: What checks are required after installation?

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