Fits: 2001 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM/LML Duramax Diesel

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 3,000 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.

Features: 

• Brand new Bosch CP3 pump
• No core charge or core to return 
• Eliminates factory fuel restriction
• Maintain desired fuel rail pressure

Includes:

• Bosch CP3 Pump

Notes: 

• The fuel pressure regulator will need to be scaled appropriately when installed in a 2001-2005 (LB7 or LLY).
• 2011-2016 will require an install kit for any CP3 Injection pump.
