I want to put the tank in the bed. But I dont like how big and bulky it is. I also dont need 31 gallons for wheelin. I dont plan to lower the height of it any, I just would like to make the width smaller. If I can get it clean enough and all of the gas fumes out to cut and weld on it. What problems might I run into sending unit wise?? What guage metal should I use to seal it back up?? I do realize that welding it and having it not leak might be a pita but id rather try that then spend 200+ for a fuel cell. Or would I be better off just looking for a smaller tank out of a car or something and making that work?
