Built this a while back. Mainly used scrap steel aside from the weldable hinge. Works great, rattles a bit too much depending on the air pressure in the tank. Rubberized truck bed liner spray finish.
Anyone have a good way to expand back out crushed jerry cans, besides driving to the mountains? I had a bit of fuel in one up around 8000 feet and when I got home it was all sucked in, and I can't get it popped back out for the life of me. Sux.
