CP3 Pump

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins High-Pressure Fuel Injection CP3 Pumps & Hardware

Restore your common-rail fuel system's operational efficiency, eliminate performance-robbing voltage and pressure drops, and supply your fuel rail with an unyielding volume of diesel with premium 2010–2018 6.7L Cummins 4th Gen CP3 pumps from Full Force Diesel. The high-pressure CP3 injection pump is the absolute heart of your 4th Generation inline-six engine block, responsible for pressurizing fuel to immense levels before routing it directly to the common-rail and electronic fuel injectors. Over years of heavy fifth-wheel towing or performance street driving, internal components undergo immense structural wear. Whether you are replacing a fatigued factory pump to restore stock reliability or seeking massive flow increases to support high-horsepower tuning parameters, choosing the correct high-pressure pump setup is mandatory to maintain absolute driveability.

Restoring Daily Dependability: Factory-Displacement Stock Upgrades

For truck owners focused on maintaining original factory specifications and long-term utility, addressing high-mileage pump wear is a critical maintenance checkpoint:

• Overcoming Sluggish Turnover: As a stock injection pump ages, its internal clearances widen, making it difficult to build rapid cranking rail pressure. This results in extended crank times, hard starts when the block is hot, and intermittent rough idling. Replacing the worn unit with an OEM-spec stock CP3 pump restores instant starting synchronization.

• Eliminating Low Pressure Defuels: A degraded factory pump will frequently fail to meet commanded pressure targets when pulling heavy loads up steep grades. This variance triggers defensive diagnostic trouble codes (such as P0087 for low fuel rail pressure) and forces the Engine Control Module (ECM) into a protective defuel limp mode. A fresh, drop-in factory-replacement pump completely eliminates these flow restrictions.

Scaling Up Performance: High-Displacement Single and Dual Pump Configurations

When your 4th Generation common-rail platform transitions past factory horsepower limits via electronic tuning, aggressive fueling profiles, or larger turbochargers, the stock pump's displacement capability is quickly outpaced:

• Single Modified Stroker Pumps: For a clean under-hood presentation that avoids the extra belt routing and plumbing footprint of a twin-pump setup, modified single CP3 pumps are the perfect engineering solution. These units bolt directly into the factory location on the front gear cover while utilizing lengthened internal cam profiles and micro-polished plungers. Available in 10mm, 12mm, and 14mm stroker configurations, they drastically increase displacement per revolution to sustain rock-solid rail pressure.

• Unyielding Dual CP3 Kits: For extreme street, heavy towing, and competition blocks requiring a massive volume of fuel, dual CP3 kits add a secondary high-pressure pump to the engine network. Driven by a low-profile billet mounting bracket system, this twin-pump matrix splits the mechanical workload entirely in half. This load-sharing longevity slashes the direct drive strain placed on your primary pump by 50% while guaranteeing perfect diesel atomization into an ultra-fine mist for complete combustion efficiency.
