Sorry gang, I've played in the archives for a couple of days and found
tons of info ... but my particular question doesn't seem to be covered
well.  Manual valves are simple but the Autostop is new to me.

With a propane tank that's not yet completely empty (stove still lights)
but has been used for cooking and fridge for several weekends of camping
... is the bleeder hose supposed to hiss (let gas escape) when the
bleeder valve is opened (remember ... AUTOSTOP) or is it supposed to
remain silent until the tank is full?

Any and all autostop info will be greatly appreciated as I haven't
filled the tank since I've had it (and it's time) and I'd like to know
it's working (or when it's not working right) before I condemn the thing
and go manual valve hunting.

Thanks,

Mike
