A-Premium Electric Fuel Pump Module Assembly for 2004–2007 GMT800 (3‑Tube Petrol) with Pressure Sensor, OEM Fit

The A-Premium Electric Fuel Pump Module Assembly with Pressure Sensor is a direct-replacement gasoline fuel pump module designed for 2004–2007 GMT800 vehicles with three fuel tube ports, restoring proper fuel delivery and pressure sensing.

This replacement module combines the electric fuel pump, integrated fuel pressure sensor, sending unit and strainer in a single boxed assembly engineered to match the original equipment layout for compatible GMT800 full-size trucks and SUVs. It is intended specifically for gasoline models that use three tube ports; it is not compatible with Flex-Fuel (E85) vehicles or models with two tube ports. Review your vehicle’s fuel neck and part numbers before ordering to ensure fitment.

Which vehicles will this A-Premium pump module fit?

The assembly is built for GMT800-era vehicles and supports multiple V8 engine options, but only gasoline models that have three fuel tube ports. Confirm your vehicle year, engine size and the number of fuel tube ports before purchasing. Use the listed reference numbers to cross-check compatibility.

How does the integrated pressure sensor help performance?

The built-in pressure sensor monitors fuel rail pressure so the engine control system can adjust delivery for consistent operation. Having the sensor integrated in the module simplifies installation and wiring compared with separate aftermarket sensors. Proper pressure feedback supports smoother starts and steadier cruising when the rest of the fuel system is healthy.

• Pre-mounted sensor matched to module plumbing for plug-and-play replacement
• Maintains OEM-type electrical connections and fuel line routing
• Helps engine management maintain target fuel pressure under load

What do I get in the box and what related parts might I need?

The package contains one complete fuel pump assembly packed in a protective box ready for installation. Depending on vehicle age and condition, consider replacing associated components at the same time to reduce future labor. Inspect seals and the fuel strainer for wear during replacement.

• Package contents: 1 x fuel pump assembly (boxed)
• Common related parts: seal ring, strainer, fuel sending unit, replacement fuel pump or pressure sensor if separated
• Verify part numbers and your vehicle’s fuel port count before fitting

Are there fitment restrictions or important notes I should know?

This assembly fits only gasoline GMT800 models with three tube ports and is not compatible with Flex-Fuel (E85) or two-port designs. Installing this part on an incompatible vehicle can prevent proper sealing or fuel delivery. Always compare reference numbers and visually confirm the fuel neck and connector layout before installation.

• NOT for Flex-Fuel (E85) or vehicles with yellow gas cap indication
• Only compatible with models listed in the product fitment details
• Check vehicle part numbers MU1639, 19256621, 88965556, etc., to confirm match
