I have an "Extended Stay" Kit fitted to my main propane tank. For those who don't know, it's a brass fitting that is added to the plumbing before the regulator. A four foot hose allows a portable propane tank to be hooked up. I have two, 7 1/2 gallon tanks and just keep refilling those while keeping my main tank full. I've done this on all three of the GMC's I've owned. My current 74 Palm Beach sat in storage for ten months. I'm now living in the coach full time but have a new development. When I open the valve on the portable tank, the propane flows and I can use the stovetop, but the next time I try to light the stove, no propane. I closed the valve to the portable tank and opened the on-board tank and I get propane. I turn off the main tank and back to the portable. Story repeats.
What's up? I used this system for a year before storing it and all was well. Can anyone shed some light on this?

Try closing all loads on the propane and then open your portable cyl with no open loads.

OK, after poking around I discover that I have a half full 7 1/2 gallon tank that is half full but I disconnected the hose and opened the valve. Nothing. The tank is new (one year old) and obviously has propane in it. I can see the dew like because it's cool here this morning and it weighs twice as much as the empty one.
Is the float stuck or something? Anyone know how to solve this?

Most extension hoses have a flow engaged check valve that blocks the hose if too much gas flows too quickly. If you opened the tank valve with the far end of the hose not attached to anything then you tripped the safety valve. It needs about a half hour without pressure on either side to open back up.

Okay, it seems as though some dirt or contamination kept the brass fitting on the end of the four foot hose kept the flow valve from opening. I cleaned out the crud and "Presto" I have gas. Wait, let's say I now can light the stove.
