Industrial Injection 21S601 Fuel Injector Line Kit 2019+ Ram 6.7L Cummins

The Industrial Injection 21S601 is a complete fuel injector line kit designed for the 2019 Ram 6.7L Cummins diesel engine. Fuel injector lines are high-pressure steel lines responsible for delivering fuel from the common rail fuel system directly to each injector. Over time, these lines can develop cracks, leaks, or stress fractures — especially in high-performance or high-mileage applications — making a quality replacement kit essential for maintaining proper fuel delivery and engine performance.

Industrial Injection is a trusted name in diesel performance and fuel system components, offering products engineered to meet or exceed OEM specifications. This kit provides everything needed to replace worn or damaged high-pressure fuel lines and restore reliable fuel system integrity.
