Low rail pressure, long cranking, or metal in the fuel system are common signs of a failing CP3 pump. The Bosch 0445020030 is a brand-new CP3 high-pressure injection pump for LLY Duramax 2004.5-2005.

Match your OE pump number and install with clean fuel and a healthy low-pressure supply so the new high-pressure pump is not damaged on startup.
