What broke

[knotical]

the air was coming from around the neck.

As others suggested, it could be the burst disk; but this phrase suggests the o-ring. Either way, it's time to get it checked out by a capable tech.

And I'd suggest finding a shop with more intelligent "fill monkeys"

You assume I didn't appreciate the extra air.

You assume I didn't appreciate the extra air.

Actually I think the assumption is that you wouldn't want to risk that kind of failure at 100ft.

Problem solved. I have a few old Al 80s that need a vis/eddy so I just swapped the valve. I'll get the steel re-filled and get the Al 80 serviced at some point in the future.

Burst disks that are rated 2,250 psi blow at about 3,500 psi.

Burst disks that are rated 3,000-3,500 psi blow at about 5,000 psi.

So what you are saying is that I now have a 144 cubic ft tank!?!

Wow. That's great

Thanks for keeping us safe Rick. You rock.

You now have the wrong burst disk for that tank... although this time the o-ring seems to have been your safety pressure relief.. next time it may not.
