DHD 700-012 LB7 Duramax High Pressure OEM Fuel Line Kit
This is a complete set of all eight high pressure fuel injector lines for your 2001-2004 LB7 Duramax. These are genuine OEM GM lines and not the cheap aftermarket alternative. It is always highly recommended to replace all of your fuel lines when swapping injectors to eliminate debris contamination.
DHD always reccomends replacing stripped, rusty or damaged fuel system hardware during service. Our LB7 Line Retainer Kit is an excellent addition to our high pressure fuel line set.
