Detailed Description

The Delphi FG2308 fuel pump module assembly is engineered for direct replacement service on compatible Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD trucks. It is an in-tank electric fuel pump module with a built-in regulator, fuel level sender, and vapor pressure sensor, helping restore proper fuel delivery and tank level reporting in one assembly. Delphi’s OE background is reflected in the module’s construction and application coverage for late-model heavy-duty trucks.

This part cross-references Spectra Premium SP4088M for the same application. Delphi FG2308 is also referenced by part numbers such as 13505232 and EFG2308.

What It Is Used For

• Restoring fuel pressure on a truck with hard-start or no-start symptoms
• Correcting fuel delivery issues caused by a weak or failing in-tank pump
• Replacing a malfunctioning fuel level sender that causes inaccurate gauge readings
• Addressing vapor pressure sensor faults tied to fuel system monitoring
• Replacing a worn module on flex-fuel Silverado 3500 HD and Sierra 3500 HD applications

Installation Notes and Tips

Fits 2011-2014 Chevrolet Silverado 3500 HD, N/A, and fits 2011-2014 GMC Sierra 3500 HD, N/A, with the 40-gallon rear fuel tank and RPO Code N2L; Mexico applications with RPO Code CV3 are also listed. Fuel tank contamination is a leading cause of premature pump failure, so Delphi recommends cleaning the tank before installing a new pump. Use of fuel tank cleaning kit FC01 is recommended. Verify connector style, outlet configuration, and tank application before installation.
