Description
Fleece Performance 6.6L Duramax CP3K Fuel Pump
Fleece Performance # FPE-DMAX-CP3K
The Fleece Performance CP3K is a modified Duramax LBZ/LMM 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, factory fitment 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) You can get the values here.
We recommend using this pump if you are doing a CP4 to CP3 Conversion on the 2011-2016 6.6L LML.
Features:
- OEM direct fitment – A true “drop-In” performance upgrade
- Built using all new components – Ensures long term reliability
- 1 Year Fleece Performance Limited Parts Warranty
- No Core Return Required
