Fuel injector lines for the 2004.5–2007 5.9L Cummins deliver high-pressure diesel fuel from the common rail to each injector. Built to withstand extreme pressure, these precision-engineered lines ensure accurate fuel delivery for efficient combustion.
Over time, lines can wear or develop leaks, especially in high-mileage or performance applications. Replacing them with quality components helps prevent fuel system failures, supports injector performance, and maintains engine reliability.
