My tank has what is called a liquid/wet leg. Not all tanks have them from what the propane guy said. It is a male connection that is valved. I would think the liquid would siphon just like anything else.
Maybe I can give Hank Hill a call.
But if you are just using it for your grill at home , wouldn't it be easier to just run a direct line to the grill area and attatch a length of rubber hose to the grill from a shut off and regulator nearby ? The hand held roofing torches we used had 15-20' rubber lines attatched to the 20 and 30 # tanks we used .

I knew someone would bring up the subject of hard piping.
I am waiting to do this. I have found a jenn-aire slide in I want to have installed in a bricked enclosure but that is to come after the pool goes in.
I use the 20# bottles for various things other than the BBQ or I probably wouldn't mess with it.
