Product Details

This Autobest fuel pump module assembly is engineered for direct replacement service on 1998-1999 Chevrolet C1500 Suburban, C2500 Suburban, K1500 Suburban, K2500 Suburban, Tahoe, and the corresponding GMC C1500 Suburban, C2500 Suburban, K1500 Suburban, and K2500 Suburban applications. The F2974A part number is also referenced in the aftermarket under cross-reference numbers such as Airtex E3963M and Delphi FG0088 for the same application family. Autobest uses top-grade components and tests pumps throughout manufacturing to help maintain consistent fuel delivery and electrical performance.

The module is designed for in-tank use and includes the fuel sending unit and tank pressure sensor, which supports accurate fuel level and system monitoring on the listed GM SUV platforms. With a 3/8-inch quick-connect outlet and 5/16-inch quick-connect inlet, this assembly is suited for vehicles that require a complete module replacement rather than a pump-only service.

Common Problems This Part Can Address

• Hard starting caused by weak or inconsistent fuel pressure
• Engine stalling from fuel delivery interruption
• Fuel gauge inaccuracies related to a worn sending unit
• Check engine concerns tied to tank pressure sensor faults
• Poor drivability from a failing in-tank pump module

Installation Notes and Tips

Verify the module code, connector style, and tank configuration before installation. This assembly is intended for vehicles with the listed GM SUV fitments, including Tahoe applications with two electrical connectors and module code GFL. Replace the tank seal during service and confirm all quick-connect fittings are fully seated before returning the vehicle to service.
