Keep fuel moving from the tank to the engine with the Delphi Fuel Pump Module Assembly FG0121, a direct-fit replacement for the 2001-2003 Chevrolet Silverado 3500 and 2001-2003 GMC Sierra 3500. This in-tank module handles the fuel-delivery job as a complete assembly, drawing fuel and feeding it to the engine's fuel system so the truck can start and run under load.
- Fuel Pump Module Assembly: a complete module that mounts in the fuel tank and delivers fuel to the engine; replaces a worn or failed original module.
