The GMC Sierra 2500HD Diesel Fuel Injector Pump by Fleece Performance, featuring the Modified CP3K, is specifically designed for 2001-2013 Duramax engines. This robust fuel injector pump ensures optimal performance by addressing common factory limitations, enhancing your vehicle's power and reliability during demanding driving conditions.

The Fleece Performance CP3K is a modified version of the Duramax LBZ CP3 injector pump, thoughtfully engineered to resolve the fuel flow restriction that typically occurs at 3,000 RPM in factory setups. This issue often leads to reduced horsepower just when you need it most. By choosing the CP3K, you're investing in consistent fuel flow and maintained rail pressure, providing a noticeable performance boost. Each pump undergoes rigorous testing on our in-house engine simulator and pump test stand, reflecting real-world operating conditions to guarantee reliability and readiness right out of the box.

Features

• Eliminates factory fuel flow restriction starting at 3,000 RPM
• Improved horsepower and torque for your Duramax engine
• Tested for performance and reliability on in-house simulators
• Duramax LBZ/LMM based for 2001-2013 models
