6.7 Cummins Venom CP3 Conversion Kit (Without Injection Pump) – BD Diesel 1050490

Protect your 2019–2020 Ram 6.7L Cummins from the costly failures associated with the factory CP4.2 high-pressure fuel pump. The BD Diesel Venom CP3 Conversion Kit lets you convert back to a proven, higher-volume Bosch CP3 pump (Duramax-style) for greater reliability, durability, and fueling capacity.

In 2019, Cummins switched from the long-proven CP3 to the CP4.2. The CP4’s lower volume output required a higher drive ratio, spinning the pump faster and increasing stress. When a CP4 fails, metal debris can contaminate the entire fuel system—injectors, rails, and lines—often leading to repair bills of $10,000 or more. This kit allows you to take advantage of the existing overdrive while installing a more robust CP3 that delivers approximately 25% more volume than the CP4, supporting both stock and performance applications.

Key Features & Benefits

• Replaces the CP4.2 with a reliable Duramax-style CP3 pump
• CP3 provides ~25% greater fuel volume than the CP4
• No tuning required
• EPA compliant (when installed as a standalone conversion; additional fuel system modifications may affect compliance)
• Includes mounting bracket, hardware, pulley, fuel lines/fittings, and Fuel Control Actuator (FCA) extension harness
• No core charge
• Straightforward installation (typically around 3 hours)

Important: This is the conversion kit only. The CP3 injection pump is not included. Pair it with a stock Duramax-style CP3 or upgrade to a high-performance BD R900 Stroker pump (part #1050651) for even greater flow.
