Carter P74778M fuel pump module for the 1997-2002 Chevrolet Express 2500 V6 4.3L, V8 5.0L or 5.7L, the 1999 Express 2500 V8 6.5L and other vehicles moves gasoline from the tank to the engine. It mounts in the tank and includes the fuel sending unit.
A failing fuel pump module can show up as hard starting, sputtering under load or an erratic fuel gauge. A fuse, a connector or the wiring can give these symptoms too, so with the engine off, start by looking at the fuel pump fuse and the wiring connector for damage; a shop can test fuel pressure. If the fuel pump assembly is the cause, this module replaces it.
This in-tank module is a direct-fit replacement for the 1997-2000 GMC Savana 3500 V8 7.4L and the 1997-2002 Chevrolet Express 1500 V6 4.3L, V8 5.0L or 5.7L, along with the Express 2500 above. The 1997-2000 GMC Savana 3500 V8 7.4L takes one module. If your van is not named here, look up its year and engine on the Buyer's Guide tab.
