Description Fits Year Make Model / Engine 2019-2024 Ram 2500 / 3500 6.7L Cummins Maintain the integrity of your high-pressure fuel system with the Industrial Injection 2019+ Ram 6.7L Fuel Injector Line Kit. Fuel lines are critical components that endure extreme pressure cycles; over time, they can become fatigued or contaminated with debris during injector swaps. This kit provides a complete set of high-quality replacement lines designed to ensure a precise, leak-free connection between your fuel rail and injectors. Constructed from durable, corrosion-resistant materials, these lines are engineered to withstand the rigorous demands of the late-model Cummins high-pressure common rail system. Whether you are replacing worn-out factory lines or performing a preventative refresh during an injector upgrade, this kit ensures consistent fuel flow and cleaner combustion for maximum engine efficiency and reliability. Part Number: 21S601 Features High-Pressure Ready: Engineered to handle the extreme injection pressures of 2019+ 6.7L Cummins engines. Precise Fitment: Designed specifically for the 5th Gen Ram head and fuel rail configuration for a secure, no-leak seal. Corrosion Resistant: Built from premium materials to resist pitting and internal scaling over long-term use. Optimal Fuel Delivery: Promotes consistent fuel flow across all six cylinders for smoother engine operation. Installation Ready: A direct replacement for factory lines, making it an essential part of any high-pressure fuel system service. Includes (1) Complete Set of (6) High-Pressure Fuel Injector Lines Notes Safety: High-pressure fuel lines are considered one-time-use components by many technicians to ensure a perfect seal; replacement is highly recommended whenever lines are removed. Application: Specifically for the 2019 and newer "New Body Style" Ram trucks. Cleanliness: Ensure the fuel rail and injector inlets are surgically clean before installing new lines to prevent premature injector failure.
