    LBZ: Lbz fuel line

    I've never dealt with this issue but I'm pretty sure you can cut them out and put a new section in also I if you were planning on putting in a lift pump I believe that fixes the issue and line collapse shouldn't happen anymore obviously there are other benefits to doing the lift pump as well...

    Pump rub?

    When I had bought my truck the transfer case had already been leaking so I had it changed but I know for a fact that the pump inside can take a shit load of punishment as long as the rub is fixed because at my friends shop they have a truck they use for well pretty much everything from plowing...

    Also I believe there is a engine oil dye you can add to your fuel without replacing all 8 seals is to add it your fuel remove the valve covers do a reassembly of the fuel lines and run the engine with a black light. Also that's for a LB7 so idk if the other engines will still work out like that...
