Thanks for the replies. I would not use a can that had ever had anything but glow fuel in it previously. I was just using the "paint thinner" can as a reference. I will ask around the club and see if anyone has an empty one and make sure there is no rust. They just looked like a good idea to doing something like KW_Counter did and strap a fuel pump to it. The more I think about it, with the potential for rust and denting the can and so on, I may just stick to plastic. There is a reason all of the manufactures I had ever seen unitl now were all plastic.
