re: Anyone have propane for their home and have an outlet outside?

We have a buried tank. They come top it off every 3 months automatically. It hasn't run out yet. It's a 500 gallon tank but they only fill it something like 80%. I think to allow for gas expansion or something. There is a regulator at the house where it enters but it's as high as it can go without destroying our appliances. This is what the propane guy told me when we had issues with our fireplace producing a tiny flame on full on. So I doubt there any way to increase it enough for a crawfish burner. I'm damn glad I started this thread. I don't have a propane tank and having a boil on Sunday. I might have not properly prepared thinking I could just get some fitting for the outlet and been ready to go. I'll table this little project when I can research everything I need to do. Thanks guys.
