I can't answer your question directly, but just did purchase one a month or so ago that is setup exactly what you are asking about. I can get some pics and try and see what was involved with it, but I don't think it was much more than an adapter to go to the larger tank, but I could be wrong. Will try and update later tonight or in the AM. I do have to say, the larger tank is nice as I know I wont be running out of gas anytime soon and it seems to be working great. Mine also sits next to my Summit Gasser so the larger tank is not a big deal.
