In this case--Is there any chance of the gauging tool falling into the tank and becoming lodged inside?
No, the gauge is just a piece of tube, it can't fall in, and propane is not pushing anything out..
If it sits in the valve, then the tank is good, if it sits on top of the o ring and not nicely in the valve, its no good.
