Thumbnail Filmstrip of Duramax 12mm Stroker CP3 High Pressure Fuel Pump S&S Diesel CP3-DMX-12 Images
Optimizing your Duramax’s fuel system is a critical step in unlocking elite performance, and the S&S Diesel 12mm Stroker CP3 High Pressure Fuel Pump represents the pinnacle of high-pressure fueling technology. Designed specifically for 2001–2010 Duramax engines, this brand-new unit is engineered to overcome the inherent limitations of factory fueling components. While standard pumps often struggle with volume as demands increase, the S&S 12mm pump provides a massive increase in displacement, ensuring your injectors never starve for fuel even under extreme stress. By integrating this pump, you are not just replacing a part; you are installing a precision-engineered solution that balances raw power with the long-term reliability S&S Diesel is known for.
- 12mm Stroker Design: Features a 46% increase in displacement compared to stock LBZ units, providing the necessary volume for high-performance applications.
- 1,000+ HP Support: Engineered with enough flow capacity to support four-digit horsepower figures on a single CP3 configuration.
- Unrestricted RPM Range: Modified to eliminate the common fuel flow restrictions that typically plague stock CP3 pumps once they reach 3,000 RPM.
- Premium Build Quality: Brand-new construction (not remanufactured) ensures maximum longevity and durability over any other pump currently on the market.
- Versatile Compatibility: Ideal for 2001–2010 Duramax models and can be utilized for LML CP3 conversions, though specific tuning may be required for optimal integration.
Beyond its impressive power ceiling, the true value of the S&S 12mm Stroker Pump lies in its ability to maintain consistent rail pressure throughout the entire power band. By removing the 3,000 RPM "bottleneck" found in factory pumps, it allows for a more linear and predictable power delivery that is essential for both competitive racing and heavy-duty performance use. Whether you are performing an LML conversion or pushing your early Duramax to its absolute limit, this CP3 pump serves as the foundational upgrade for any enthusiast demanding more flow and higher reliability from a single-pump setup.
Notes:
- Tuning is REQUIRED if installing on 2001-2005 LB7 and LLY engines
- Fitment on LB7's requires you to modify the regulator connectors to make them fit.
