Man you guys are good, don't miss anything, well it used to be the red can below, but then all you started bringing things up like, fumes, safety, and death, so I upgraded to this closed black tank I picked up at that swap meet I was talking about in another post for $5.00 bucks, the owner had no idea what it came off of, but it had a nipple on the bottom so it works perfect. It's kinda difficult to see (jk) but it's simply held on with WHITE zip ties, MacGyver style, (member him?).
