Subject: Re: Ruben's tube and propane
Zig and Dave Maiullo both run their tubes off propane using small 7 to
10 lb tanks with the standard pressure regulators. While you need
different orfices for things like stoves and water heaters for the
different gasses, I think you will find that the Rueben's tube is pretty
forgiving in this regard. So, you should be able to use it with either
gas. I would suggest getting the quick couplers for ease of attaching
the tank to the tube. ( They look and act the same as the couplers for
high pressure air hoses).
