Product description
The Diesel Auto Power Complete Fuel Injector Line Set for the GM 6.6L Duramax LML and LGH diesel engines is a high-quality OEM replacement kit designed to supply fuel to all eight cylinders (1/8, 2/7, 3/6, 4/5) for optimal combustion and engine performance. This set includes four high-pressure fuel lines (part numbers 12670460, 12670468, 12670469, 12670471), each engineered to meet or exceed OEM specifications. These lines address common issues like leaks, cracks, or corrosion in aging lines, ensuring consistent fuel system pressure and preventing contamination. Constructed from durable, high-pressure-rated materials, they withstand demanding conditions, making them ideal for both stock and performance applications. As direct-fit replacements, they offer easy installation and reliable operation. Backed by Diesel Auto Power’s commitment to quality, this complete injector line set is essential for restoring fuel system integrity and efficiency in Duramax LML engines. Note: The set covers all eight cylinders, with each part number servicing a pair of cylinders (two lines per part number).
