I'm pretty sure there's a fac article on this install. Several vendors here sell kits. They include sending unit and mounting hardware. We used the plastic tank and I wasn't real thrilled with it. When tightening down the straps one side of the tank half collapsed. It seemed like I barely had the strap tight enuf to hold it up. Also the width of the mounting flange was a little narrow, so the tank was prone to slide off the flange on one side of the frame or the other. We grafted in a fill door from a Blazer before the truck got painted. It was a little tricky figureing where to cut. What made it easy for me was having a spare thrashed bed to cut on. It took about 3 tries on the outer, and 4 on the inner to get it right. Then made measurements and only cut the good bed once. I've got pics of the fill door, but not much on the tank itself.

Edit** Many thanks to boardmember "jose" for finding, cutting out, and shipping the door and fill spout!
