Sorry BF, I don't. I was in aviation in the military and have got fuel from them and thought how cool is that. My helicopters stub wings had a bladder in each as well and the bottom 1/3 was able (in theory) to take direct hits and reseal.
Although now I wonder how much those farm truck tanks hold. You know the one I mean? They sit next to the cab in the bed. Have a gas station type handle.
