Bosch 66077 fuel pump module for the 2006 Chevrolet Silverado 1500 V8 5.3L and other vehicles delivers fuel from the tank to the engine's injection system. This in-tank module, also called a fuel pump assembly, pairs an electric pump with a strainer, filter and fuel sending unit.
Hard starting, stalling or a whine from the fuel tank can mean the pump is wearing out. A clogged fuel filter, a bad fuel pump relay or damaged wiring can be behind the same signs, so find the cause before buying. If the module is at fault, this one replaces the pump, strainer and sending unit together.
It fits the 2006 Chevrolet Silverado 1500 V8 5.3L, the 2006 GMC Sierra 1500 V8 5.3L, the 2007 Chevrolet Silverado 1500 Classic V8 5.3L and more, and each takes one. If your truck is not named here, look up its year and engine on the Buyer's Guide tab.
