01-10 GM 6.6L Duramax Fleece Performance Modified CP3K Pump

List price: $1,237.95

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.

NOTE: The fuel pressure regulator will need to be scaled appropriately when installed in a 2001-2005 (LB7 or LLY)

*DOES NOT include any sealing washers.


  • Eliminates Factory Fuel Flow Restriction
  • Maintains Rail Pressure Through Entire RPM Range
  • Supports 650HP
