Delphi FG0121 fuel pump module for the 2001-2003 Chevrolet Silverado 3500 V8 6.0L or 8.1L and other vehicles sends fuel from the tank to the engine. Also called a fuel pump assembly, it is built to Delphi's OE standards.
Hard starting, stalling or a gas gauge that reads wrong can mean the pump or float arm is wearing out. Before you replace the module, rule out a blown fuse, a faulty relay and a restricted fuel filter, since each of those can also leave the engine hard to start.
It fits the 2001-2003 Chevrolet Silverado 3500 V8 6.0L or 8.1L and the 2001-2003 GMC Sierra 3500 V8 6.0L or 8.1L, and each takes one module.
One fuel pump module with float arm, seal, splices, wire harness and an instruction sheet.
