Detailed Description

Delphi FG0159 is engineered for 2001-2002 Chevrolet Express 3500 and 2001-2002 GMC Savana 3500 models equipped with Federal Emission System, RPO code NF4 or NF2, 35 gallon tank, RPO code NL1, and cutaway chassis. This fuel pump module assembly is built for in-tank service and includes the fuel pump, sender, seal, strainer, float arm, splices, wire harness, and instruction sheet to support a complete fuel system repair. Delphi’s OE heritage and broad aftermarket coverage are reflected in the module’s fit, materials, and electrical design. This part cross-references Airtex Fuel Pumps E3551M and Carter P74979M for the same application.

Common Repair Applications

• Hard starting caused by low fuel pressure
• Engine stalling from inconsistent fuel delivery
• Fuel gauge readings that no longer track tank level correctly
• Loss of pump output in an in-tank gasoline system
• Fuel delivery issues on Chevrolet Express 3500 and GMC Savana 3500 cutaway chassis models

Installation Notes

Before installing a replacement pump module, clean the fuel tank to reduce the risk of contamination-related failure. Delphi recommends using fuel tank cleaning kit FC01 for this application. Verify the vehicle’s emission system, RPO codes, and 35 gallon tank configuration before installation. Confirm all electrical and quick-connect connections are secure and inspect the tank seal surface before reassembly.

Quality Assurance

Delphi builds this fuel pump module with OE-based engineering and application knowledge developed through long-term original equipment supply. The FG0159 is a standard replacement part designed for the specified Chevrolet and GMC applications and is supported by Delphi’s OE-focused manufacturing background.
