If you re-read his statements he has 3 gauges. 2 Low pressure and 1 high pressure for the the tank. Neither of the 2 low press gauges dropped (1 actually went up) the 3rd gauge (high pressure tank gauge) went down and almost bottomed out. Am I missing something.

I have a 2 gauges on a spare tank i use for purging. I close the valve on my tank, I can come back a month later and neither gauge has moved.

If he had a bad connection between his tank and regulator, and the leak was big enough to lose a tank over night, as soon as he closed his tank valve the needle on the high pressure gauge would bottom out almost instantly. He said his high pressure gauge bottomed out after ~24 hours, indicating a small leak on the high pressure side. The amount of gas left in the regulator after closing the tank valve is probably a few cc. It wouldn't take much of a leak to lose that over 24 hours.

So, he does have a leak on the high pressure side of the regulator somewhere, but it's small. Actually, based on his description, the low pressure gauge that went up in pressure could be caused by gas getting past the diaphragm of that regulator and raising the pressure on the low pressure side.

Well good luck, hope you find it.
