DDP DDPNCP3-33212 DURAMAX 01-10 BRAND NEW 12MM STROKER CP3

Duramax 01-10: Brand New 12mm STROKER CP3 pump sold with no core charge. This pump is capable of supporting over 1,000 RWHP with proper supporting modifications. Full fuel delivery to 6,000 RPM. New OEM unmodified FCA for improved tunability.

• 12mm Stroker CP3 Pump: This indicates the pump has been modified ("stroked") to deliver more fuel volume compared to a stock CP3 pump, which is the standard fuel injection pump used in Duramax engines.
• Brand New, Not Remanufactured: This pump is manufactured and sold as a new unit, not a rebuilt one.
• Supports High Horsepower: It is designed to support applications with up to 1,000+ rear wheel horsepower (RWHP) with appropriate supporting modifications.
• Increased Fuel Volume: It produces 75% more fuel volume than a stock CP3 pump.
• Full Fuel Delivery to 6,000 RPM: It can supply sufficient fuel for reliable performance at engine speeds up to 6,000 RPM.
• Improved Tunability: It features a new OEM unmodified Fuel Control Actuator (FCA) for enhanced tunability, allowing for smoother adjustments.
• No Core Charge: The pump is sold with no core charge, simplifying the purchase and installation process.
• Lift Pump Recommendation: For optimal performance, a 200 GPH (or larger) lift pump set at 8-12 psi is recommended.
• Considerations for Installation: If installing on LB7 or LLY models, the FPR/FCA table will require rescaling for compatibility with the LBZ CP3, which should be manageable for a competent custom tuner.
