2007.5+ Cummins Ordnance 650 CP3 w/ Gen2 SP3000 Mechanical Supply Pump (6.7C-CP3-ORD650-SP)

Fits

Note: 2019+ models require a CP3 Conversion Kit to replace the factory CP4 pump.

The Cummins Ordnance 650 CP3 (SP) is a competition-grade pump designed for high-RPM reliability and extreme performance. Starting as a brand-new Bosch CP3, each unit is heavily modified and finished in a durable Cerakote to prevent corrosion. Featuring a massive 1,850 mm3/rev displacement and 650 L/hr flow rate, it supports over 1,200+ HP. This model includes the Gen2 SP3000 Mechanical Supply Pump, an integrated feeder pump that ensures the high-pressure side never starves at engine speeds exceeding 5,000 RPM.

*IMPORTANT* Please read the "Additional Information" section.

Mechanical Supply Requirements: The SP3000 pump moves a massive volume of fuel (3,000 L/hr). To properly manage this volume and maintain the required 140–160 PSI inlet pressure, an S&S Regulated Filter Head is mandatory.

• Operating this pump without a regulated feed can damage internal seals or fuel lines due to uncontrolled supply volume.
• Custom tuning is mandatory. Adjustments to the Fuel Control Actuator (FCA) and the volume tables are required to ensure proper idle quality and rail pressure management.
• Requires a CP3 Conversion Kit to replace the factory CP4.2 pump.
• 6.7L-based pumps can also be used on 2003–2007 5.9L Cummins engines, though they require a high-pressure line adaptation kit.
• Due to the integrated Gen2 SP3000 supply pump, this unit is significantly longer than a standard CP3, measuring 171 mm (6.73 inches) from the front mounting cover to the rear of the pump. While this is a direct fit for most factory engine bays, please verify clearance if you are performing a custom engine swap or have a modified firewall/chassis configuration.
• Regulated Feed is designed for use with an external regulator (such as the S&S Regulated Filter Head) to manage high-volume flow.
