Bosch 67378 fuel pump module for the 1998-2003 Chevrolet Blazer V6 4.3L and other vehicles moves fuel from inside the tank to the fuel injection system. This in-tank electric module, also called a fuel pump assembly, is built on the same production lines and tested to the same quality standards as Bosch OE fuel pumps.
- Patented Turbine Pump technology virtually eliminates the fuel pulsation, noise and hot-start problems associated with older pump designs
- Designed to operate in extreme temperatures and under low fuel conditions
- Every pump is function tested at the end of the production line
- Two layers of filtration protect the pump from debris and fuel system contamination
- Electromagnetic shielding prevents on-board electronic interference from the fuel pump

A worn pump can show up as hard starting, sputtering or stalling, or a louder whine from the tank, though each of those can have other causes. Before replacing the module, look at the fuel pump fuse with the ignition off, and leave electrical supply and fuel pressure tests to a shop, since a blown fuse or a wiring fault can look much the same.
