Fleece Performance CP3K High-Pressure Fuel Pump for 2001-2016 Chevrolet/GMC (6.6L)
$1,349.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD trucks equipped with the 6.6L Duramax diesel engine.
The Fleece Performance CP3K is a modified high-pressure fuel pump based on the proven Duramax LBZ platform. Designed to solve the notorious fuel flow restriction that occurs at 3,000+ RPM, this pump ensures your fuel rail pressure remains stable through the entire power band. While factory CP3 pumps often suffer from pressure drop-off at high RPMs—leading to lost horsepower—the CP3K provides the consistent delivery needed for performance applications.
This pump is a cost-effective alternative to dual-pump setups for enthusiasts looking to maintain rail pressure without the complexity of additional hardware. For 2001-2005 (LB7 and LLY) applications, the fuel pressure regulator must be scaled via tuning for proper operation.
- Manufacturer Part Number: FPE-DMAX-CP3K
- Base Platform: LBZ/LMM CP3
- Function: Eliminates factory flow restrictions starting at 3,000 RPM
- Benefit: Maintains desired rail pressure for consistent horsepower
- Fitment Note: Requires regulator scaling for LB7 and LLY models (2001-2005)
