    I have a 2000 Chevy with the 6.2 diesel in it. I have a fuel leak in the area right under the drivers door.
    I am guessing it has a steel line. Can I just cut out the bad spot and replace it with a good grade rubber line? Or is it under a high pressure and needs a steel line?
    I am new to dieselsand want to make sure I fix it the best way.

    im not 100% sure but that should be lift pump pressure only. rubber should be ok when i worked on big trucks the lines were rubber from the tank to the lift pump and then steel from lift pump to injector pump.

    I had a 91 cummins with a steel fuel line leak, I just put rubber hose over the steel and hose clamped it. Never had a problem.
