I need to install a water tank and pump into my UZJ100. I don't want to get into changing out the fuel tank to make room for the combo tank by Long Ranger that fits. I really liked the setup on the Desert 80 article in the Overland Journal. I am thinking of using a "fat sack" ballast bladder from my Ski Boat, but would be interested in a poly tank that would fit behind the front row seats. Anyone know where I can find one? Where would you mount the pump? What type of tubing would you use? Any advice would be much appriciated.
