Looks like my TnT cylinders are finally ready & will be shipping on Monday along with new in/out/tank hoses that have the right fittings. Of course it looks like mother nature doesn't like that idea. It's been nice & in the high 50's or so the past few days. By the time the stuff is suppose to show up on Wednesday the high is going to be in the low 20's lows in the negative numbers, and even worse by the weekend. Not sure if my new torpedo heater will be enough to get me out to the shop to get it installed.
