Thanks, that is good info. I think I bought a roll of about 35 feet when we installed it, and I'm sure they gave me the cheapest that you could use. The line the propane company used looks the same as what I used, but it may be thicker. I will have to use whatever the hardware store has, as they will have to make the ends for me. I don't have a flaring tool.
