The Mopar 5093088AA Fuel Injector Return Line is a genuine OEM replacement fuel system component designed for 2003-2007 Dodge Ram trucks equipped with the legendary 5.9L Common Rail Cummins diesel engine. Engineered to factory specifications, this fuel return line maintains proper fuel return flow from the injector system back to the fuel filter housing, helping ensure reliable fuel system operation and consistent engine performance.
Over time, fuel return lines can become damaged, corroded, or develop leaks that may contribute to fuel system issues, hard starts, fuel odor, reduced performance, and drivability concerns. The Mopar 5093088AA return line is manufactured for direct-fit installation and provides the durability, leak resistance, and reliability required for high-pressure common rail diesel applications.
This OEM fuel return line connects from the rear of the cylinder head to the fuel filter housing, restoring factory fuel return operation and helping maintain proper fuel system integrity.
