Detailed Description

Delphi FG0158 fuel pump module assembly is engineered for in-tank gasoline fuel delivery and includes the pump module, float arm, seal, splices, wire harness, and instruction sheet. It is built for select 2001-2002 Chevrolet Express 3500 and 2001-2002 GMC Savana 3500 applications with California Emission System, RPO Code NC1, 35 gallon tank, RPO Code NL1, and Cutaway Chassis configurations. Delphi’s OE-focused manufacturing background is reflected in the module design, which combines fuel delivery, level sensing, and vapor pressure sensing in one service part. This part cross-references Airtex Fuel Pumps E3568M and Carter P74978M for the same application. Delphi FG0158 is a direct-fit fuel pump module assembly for Chevrolet Express 3500 and GMC Savana 3500 service where the original in-tank unit has failed or fuel pressure has dropped.

What It Helps Address

• Hard starting caused by weak or failing fuel delivery
• Engine stalling from inconsistent fuel pressure
• Fuel gauge inaccuracies from a worn sender assembly
• Fuel pressure loss in high-demand driving conditions
• Driveability issues tied to a contaminated or worn in-tank pump module

Installation Notes and Tips

Before installing Delphi FG0158, clean the fuel tank thoroughly. Delphi notes that fuel tank contamination is a leading cause of premature fuel pump failure, and recommends using fuel tank cleaning kit FC01 before replacing the module. Confirm the vehicle is a 2001-2002 Chevrolet Express 3500 or 2001-2002 GMC Savana 3500 with the listed California Emission System, tank, and cutaway chassis configuration before installation. Verify electrical connections, outlet routing, and seal placement during service.

Quality Assurance

Delphi builds this fuel pump module assembly using OE experience and aftermarket application knowledge developed over decades of supplying major automakers. The FG0158 is a standard replacement part designed for consistent fuel delivery, sender function, and fitment on the specified Chevrolet Express 3500 and GMC Savana 3500 applications.
