Crap!!! Thanks for the replies! I thought I had sorted it out and reattached the gas line, and clamped it again and could not hear any leak. Soapy water, did not see any bubbles. Tank gauge seemed to be holding steady. Left to go eat dinner, came back and the tank was empty!!! Gutted, as the place where I took it to get it filled has to send it out to get filled and it takes over a week. Was hoping to serve it this weekend at my daughters baptism reception.
