That's the key. For the auto-stop valve, it must be fully open. But the reason propane jockeys don't know to do that is the typical (99.9% of tanks) bleeder valve needs to be open just a crack to vent when they fill the tank. When they see propane from the bleeder, it is full. For the auto-stop to shut off the valve automatically, it must be fully open. So two reasons to replace the auto-stop with a regular fill valve and a regular bleeder valve: (1) the auto-stops are very old and may be failing, and (2) propane guys will know how to fill the tank without coaching.
