I too acquired a completely functioning unit with the locking refill port on the tank. Has anyone located a photo of what the wrench key looks like?
Wondering if I can remove the pump to n remove the fill port and decipher the pin sequence.

Thanks in advance

This Patent might give ya a better idea of how to get it open/off.

Bottle Filler Patent

I SEEN ONE OF TOOLS LAST YEAR AT HERSHEY THAT WENT INTO THE FIL-PRUF BOTTLES TO FILL THE BOTTLE AT THE TOP. IT HAD THE GARGOYLE LOGO ON IT. THE PRICE WAS $500.00
