Product Description
Dorman 904-329 Fuel Injector Line (Cylinders 2 & 4) for 2007.5-2018 Dodge Ram 6.7L Cummins
The Dorman 904-329 Fuel Injector Line is a direct replacement high-pressure fuel line designed for cylinders 2 and 4 on 2007.5-2018 Dodge Ram trucks equipped with the 6.7L Cummins diesel engine. Precision-engineered to match the fit, function, and performance of the factory fuel injector line, this replacement component helps restore proper fuel delivery and maintain the reliability of your common rail fuel system.
Because fuel injector lines utilize crush-style sealing surfaces that are designed for one-time use, replacing the entire line is necessary when servicing the fuel system or replacing injectors. Dorman manufactures the 904-329 using hardened steel construction capable of withstanding fuel pressures up to 29,000 PSI, providing the durability and sealing performance required in modern high-pressure diesel fuel systems.
Designed as a cost-effective alternative to dealership replacement parts, the Dorman 904-329 includes the necessary vehicle-specific mounting provisions for a straightforward installation while delivering dependable long-term performance.
