I had some Questions about replacing my Injectors, I know I will need new Washers to go under the injectors, and I have read and have been told how to properly bleed the air out of the system. When I have the injectors out, should I replace the Injector Over flow line, the Cloth covered line that goes form injector to injector? I dont know if there is anything wrong with the current ones, but I assume that they get changed with the injectors, correct?
