GM LB7 High Pressure Fuel Line Set

Replacing the high pressure injector fuel lines while doing your injector job will prolong the life of your injectors. These lines will build up with rust and debris, and if not cleaned out properly, the left over debris will plug up your newly installed injectors. Also, if they are pitted or corroded, we suggest replacing them.
