The Fleece Performance CP3K is a modified Duramax LBZ CP3 designed to eliminate the factory fuel flow restriction that begins at 3,000 RPM. If you have a stock CP3 pump you are losing fuel flow and rail pressure after 3000 RPM, which correlates to lost horsepower when you need it most. This cost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM range.



  • Brand new Bosch CP3
  • No core charge or core to return



The fuel pressure regulator will need to be scaled appropriately when installed in a 2001-2005 (LB7 or LLY). You can get the values here.
