We used an aftermarket poly tank kit from eBay. They set them up (for my truck at least) from a Burb. Pretty easy install. Did have to cut the spare tire stuff out and we located the filler cap off to the drivers side in the bed. I used a marine filler cap with the 2 hole keys. For right now the old filler neck is still hanging out. Its not connected to anything, just keeping the rain out. Once the day comes for repaint I am going to get it patched.
