Bosch 0986437303 diesel fuel injector pump for the 2001-2004 Chevrolet Silverado 2500 HD V8 6.6L and other vehicles is a common rail pump that sends pressurized diesel fuel toward the injectors.
A worn diesel fuel injector pump can show up as hard starting, rough running or a loss of power. With the engine off and cool, look over the pump and its fittings for fuel seepage or wet residue. Filters, injectors and wiring can give the same symptoms, so pin down the cause before you buy a pump.
This Bosch diesel fuel injector pump fits the 2001-2004 Chevrolet Silverado 3500 V8 6.6L, the 2001-2004 GMC Sierra 2500 HD V8 6.6L and other vehicles.
