Restore proper high-pressure fuel delivery and dependable fuel system performance in your GM/Chevrolet 6.6L Duramax LB7 with the Grizzly GA93722 Fuel Injection Line Kit for Cylinders 4 and 5. Designed as a direct replacement high-pressure injector line assembly, the GA93722 helps maintain proper fuel pressure, injector sealing, and reliable common rail fuel system operation for your Duramax diesel truck. High-pressure fuel injection lines are critical for delivering precise fuel volume and pressure from the fuel rail to the injectors. Damaged, leaking, or contaminated injector lines can contribute to drivability issues, fuel leaks, pressure loss, rough engine operation, or reduced performance. The Grizzly GA93722 is built to meet or exceed OEM specifications for dependable fitment, sealing integrity, and long service life in demanding towing and hauling applications.
