Detailed Description

Delphi FG0122 is engineered as a direct replacement fuel pump module assembly for Silverado 3500 and Sierra 3500 applications that require an in-tank gas fuel delivery unit. Delphi draws on OE heritage and supplier experience with major automakers, and that background is reflected in the module’s construction, electrical layout, and integrated fuel level sender. The assembly is designed to restore fuel delivery and tank-level reporting in one service part, making it a practical choice for 2001-2003 Chevrolet Silverado 3500 and 2001-2003 GMC Sierra 3500 trucks with California Emission System and RPO NB6.

This part cross-references Airtex Fuel Pumps E3500M and Bosch 67305 for the same application. Part number FG0122 is also referenced in aftermarket catalogs under related numbers such as EFG0122 and SP6612M.

Common Problems It Can Address

• Hard starting caused by weak or inconsistent fuel pressure
• Engine stalling from fuel delivery loss inside the tank
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel starvation under load from a failing pump module
• Contamination-related pump wear when the tank has debris or residue

Installation Notes and Tips

Before installing FG0122, clean the fuel tank thoroughly to reduce the risk of premature pump failure from contamination. Delphi notes that fuel tank contamination is a leading cause of early pump wear, and use of fuel tank cleaning kit FC01 is recommended. Verify the vehicle’s emission system, RPO code NB6, and tank configuration before installation. Confirm electrical connector style, outlet routing, and seal condition during service.

Quality Assurance

Delphi builds this fuel pump module with OE experience and application knowledge developed through decades of supplying major automakers. The FG0122 is a standard replacement part designed to meet the needs of Silverado 3500 and Sierra 3500 fuel system service with OE-style fit and function.
