S&S Diesel Motorsport high pressure CP3 pumps for the 5.9 and 6.7 Cummins platform. Available in a full range of configurations from the entry-level SuperSport through the maximum-output 14mm High Speed with integrated SP3000 supply pump — covering everything from mild street builds to full competition applications pushing 3,000 HP and beyond.

All pumps are brand new — not remanufactured. Selecting the correct pump depends on your injector size, horsepower goals, rail pressure target, and turbo configuration. Contact us at info@hardwayperformance.com with your build details and we will help you select the right pump for your combination.

Available configurations:

Cummins SuperSport CP3 — New. Entry-level performance pump optimized for higher output above 3,500 RPM. The ideal first upgrade for a street-driven Cummins looking for increased rail pressure and fuel delivery over stock.

Cummins 10mm CP3 — New. 1,325 mm³/rev displacement. Significant step up in fuel volume over the SuperSport for trucks with injector upgrades and turbo modifications requiring more consistent rail pressure across the RPM range.

Cummins 10mm High Speed CP3 — New. 1,325 mm³/rev displacement, high speed optimized. Same displacement as the 10mm with high speed internal components for applications demanding faster pump response and sustained rail pressure at elevated RPM.

Cummins 12mm CP3 — New. 1,590 mm³/rev displacement. Increased fueling capacity for more aggressive builds running larger injectors, compound turbos, or high rail pressure targets.

Cummins 12mm High Speed CP3 — New. 1,590 mm³/rev displacement, high speed optimized. High speed variant for demanding builds requiring maximum 12mm displacement at sustained high RPM.

Cummins 12mm High Speed CP3 w/ SP3000 Supply Pump — New. 1,590 mm³/rev displacement, high speed optimized with integrated SP3000 supply pump delivering 3,000 L/hr. For builds where lift pump flow has become a limiting factor on fuel delivery.

Cummins 14mm CP3 — New. 1,850 mm³/rev displacement. Serious high-output pump for fully built Cummins engines pushing the upper limits of common rail fueling.

Cummins 14mm High Speed CP3 — New. 1,850 mm³/rev displacement, high speed optimized. Maximum displacement high speed pump for full competition Cummins applications.

Cummins 14mm High Speed CP3 w/ SP3000 Supply Pump — New. 1,850 mm³/rev displacement, high speed optimized with integrated SP3000 supply pump delivering 3,000 L/hr. The top of the S&S Cummins lineup — maximum fuel delivery for the most demanding compound turbo and competition builds where both pump output and supply flow are critical.

Custom high pressure pumps supporting 3,000 HP and beyond are also available. For serious inquiries contact us directly at info@hardwayperformance.com.
