A-Premium Electric Fuel Pump Module Assembly for GMT800 SUVs — 2004-2007 three-port with built-in pressure sensor

The A-Premium Electric Fuel Pump Module Assembly with integrated pressure sensor is a direct-replacement fuel module engineered to restore proper fuel delivery in compatible 2004–2007 GMT800 gasoline SUVs.

If your Chevrolet Tahoe, GMC Yukon, or Cadillac Escalade (GMT800 classic-body, gasoline models with three tube ports) is showing signs of fuel delivery trouble, this A-Premium assembly replaces the entire in-tank module so you don’t have to swap multiple components. It includes the pump, filter/strainer, fuel level sender provisions and a built-in pressure sensor to match OE-style functionality. Before ordering, confirm your vehicle uses a gasoline engine with three tube ports and is not a Flex-Fuel (E85) model.

How does this module restore fuel system performance?

This assembly replaces the worn or failed in-tank unit, providing a new electric pump and pressure sensor to re-establish consistent fuel pressure and supply. With a complete module swap you avoid diagnosing and replacing several individual parts, saving time and reducing installation complexity.

• Includes pump, strainer, and sender mounting points for a single installation.
• Built-in pressure sensor helps maintain proper fuel rail pressure readings.
• Designed to match factory electrical and plumbing connections for GMT800 three-port tanks.

Will this fit my vehicle and what should I check before buying?

This part fits 2004–2007 Chevrolet Tahoe V8 (4.8L/5.3L), GMC Yukon V8 (4.8L/5.3L/6.0L/6.2L), and Cadillac Escalade V8 (5.3L/6.0L/6.2L) gasoline models that use a three-tube fuel tank configuration. It does not fit Flex-Fuel (E85) vehicles or tanks with two tube ports, and it is intended for GMT800 classic-body vehicles only.

• Verify your vehicle year, model, and engine size match the listed fitment.
• Confirm your fuel tank has three tube ports (not two) and that the gas cap is not the yellow Flex-Fuel type.
• Compare part references (MU1639, 19256621, 88965556, 19207716) with your current module before ordering.

What’s included and what related parts might I need?

The boxed package contains one fuel pump assembly module ready for installation. Depending on the age or condition of surrounding components, you may also want to replace or inspect the seal ring, fuel strainer, and fuel sending unit to ensure a leak-free and reliable install.

• Package contents: 1 x fuel pump assembly in box packaging.
• Common related parts: seal ring, strainer, fuel pressure sensor, and sending unit.
• Recommended: inspect wiring harness and fuel lines during replacement to prevent future failures.

How difficult is installation and what tools or precautions are recommended?

Installation requires removing the fuel tank or accessing the tank’s service access if available; basic mechanical skills and a few common tools are typically needed. Because fuel system work involves flammable liquids, take safety precautions: relieve fuel pressure, work in a well-ventilated area, and avoid sparks or open flames.

• Essential tools: socket set, fuel line disconnect tools, screwdriver set, and torque wrench if required.
• Safety: depressurize fuel rail, disconnect battery, and work outdoors or in ventilated space.
• If unsure, have a qualified technician perform the replacement to ensure proper sealing and calibration.

Who this product is for: Technically inclined owners and independent mechanics who need a complete, OE-style replacement fuel module for GMT800 Chevrolet Tahoe, GMC Yukon, or Cadillac Escalade gasoline models (2004–2007) with three-tube tanks. Choose this A-Premium assembly when you want a single, ready-to-install unit that replaces the pump and pressure sensor together; avoid ordering if your vehicle is Flex-Fuel (E85) or has a two-port tank. Always confirm fitment and part numbers before purchase to ensure compatibility.
