I have a 2002 GMC Sierra 2500 HD Duramax 4x4 crew cab and tow a Komfort 25FSG 5th wheel. Stock fuel tank is 25 gallons and that doesn't give me a whole lot of range so want to add an aux tank in the bed. Ideally, I would like something that is fairly easy to remove as I just don't need the extra capacity all the time and can use the room when not towing. I've decided on a 30-40 gallon tank; now, I need to figure out the best method of fuel transfer. I've talked to several people and have basically narrowed it down to an electric transfer pump that you manually turn on and off when you need to refill the main tank. The other method that I've seen is to gravity-feed from the aux to the main. Northern Tool has a kit that you put in line on the filler neck of the main tank to do this. One of my uncles has used both methods and liked both. The main down side that I can see with the gravity-feed method is that it seems to be pretty permanent whereas the electric transfer system can be easily plugged off and the tank removed when not needed. Any ideas, opinions, criticisms? Many thanks.
