4th Gen 6.7L Cummins Fuel System

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins Fuel System Upgrades & Parts

Maximize horsepower, restore crisp throttle response, and safeguard your high-pressure common-rail network against catastrophic failure with premium 2010–2018 6.7L Cummins 4th Gen fuel system parts from Full Force Diesel. The 4th Generation Dodge Ram HD trucks are celebrated for their incredible towing power, but their advanced high-pressure common-rail (HPCR) injection systems leave zero room for fuel starvation, air entrainment, or moisture contamination. Operating at pressures reaching up to 29,000+ psi, components like your fuel injectors and high-pressure injection pump require a flawless supply of clean, pressurized diesel. Upgrading your fuel delivery system is the absolute best way to protect your investment and support clean, efficient combustion.

Advanced Lift Pumps & Essential Filtration Upgrades

The foundation of a reliable 4th Gen 6.7L Cummins is a steady supply of pure, air-free fuel to the engine bay. While Ram updated these trucks with a factory dual-filter setup starting in 2013 to improve water separation, the in-tank lift pump remains a weak link when you add aggressive tuning or heavy towing demands.

• Frame-Mounted Fuel Systems: Installing a premium aftermarket fuel-air separation system (such as FASS or AirDog) is the ultimate upgrade for any 4th Gen. These chassis-mounted systems feature high-efficiency filtration and dedicated water separators to continuously sweep out air, moisture, and microscopic debris before it ever reaches your expensive high-pressure fuel components.

• Extending Injector Life: By feeding your high-pressure pump a constant, positive pressure flow of pure diesel, you eliminate the fuel cavitation and starvation that causes premature wear on injector tips and internal check valves.

The Legendary CP3 High-Pressure Pump & Common-Rail Injectors

Unlike later model years that transitioned to the notoriously fragile CP4 pump design, the 2010–2018 4th Gen 6.7L Cummins proudly features the rock-solid Bosch CP3 high-pressure injection pump. We carry a complete line of replacement and high-performance fuel components:

• OEM & Upgraded Bosch CP3 Pumps: If your factory CP3 is struggling to maintain commanded rail pressure under load, we offer direct-fit stock replacements, high-displacement modified CP3 pumps for high-horsepower builds, and dual-pump kits for maximum fueling requirements.

• Precision Common-Rail Injectors: If your truck is suffering from hard cold starts, white exhaust smoke, rough idling, or high injector return rates, it is time for a replacement. We stock factory-remanufactured Bosch injectors as well as premium aftermarket performance injectors with modified nozzles to deliver a clean, highly atomized fuel spray.

• Fuel Rails, Connector Tubes & Lines: To support increased fuel volume, we carry high-flow fuel rails, heavy-duty fuel injector connector tubes, and replacement high-pressure lines to ensure leak-free, high-pressure operation.

At Full Force Diesel, we remove the guesswork from upgrading your 4th Gen Ram drivetrain. Explore our 2010–2018 6.7L Cummins frame-mounted lift pumps, replacement fuel filters, injectors, CP3 pumps, and fuel pressure regulators above to find the exact parts engineered for your truck.
