    I'm in the process of removing the bed (CC Dually), I have a rear tank that has to come out. If I disconnect the fuel lines from the tank, I'll get air in the lines up to the fuel switch (which is switched to the front tanks now).

    What would be the procedure to purge the air once the tank is reinstalled?

    Depends on how your axuiliary tank is setup. If your aux simply pumps fuel into one of the other tanks, I wouldnt worry too much- those usually have self priming fuel pumps.

    It's set up like a stock factory tank (I think it actually came out of a suburban)...

    Wait, let me get this straight- You have 3 fuel tanks right now? if it doesnt have an electric prime pump, it will probably let in air one way or another.

    Yup, 3... /forums/images/graemlins/grin.gif Anyway, I was able to get to the nuts in the frame without completely disconnecting the tank. So no worries. Thanks for the help though /forums/images/graemlins/thumb.gif
