This is the Bosch 0445020105, a new CP3 high-pressure fuel pump, not a rebuild, for the 2006 to 2010 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L Duramax. It covers both the LBZ (VIN code D, 2006 to 2007) and the LMM (VIN code 6, 2007.5 to 2010). It replaces GM 97361351 and the earlier Bosch number 0445020037. The Bosch remanufactured version of the same pump is 0986437332, and GM’s remanufactured pump number is 97780161.

A tired CP3 shows up as low rail pressure under load, a P0087 code, hard starting or an engine that stalls under load. Rule out the cheap things first: a plugged fuel filter, air getting into the supply side and a failing fuel pressure regulator on the pump cause the same complaint. 2006 is a split year. A 2006 model year truck with VIN code 2 normally carries the LBZ fuel system and takes this pump, not the 2004.5 to 2005 LLY pump (Bosch 0445020030). Read the number on your old pump to be sure.
