HPA tank question

[Lift-off Oversteer]

I have Ninja Regulator on 13ci tank. I was filling it with Nitrogen from a bulk HVAC tank. when I opened the Valve, it start filling got to about 2000 psi on the tank gauge then. started leaking from every where but the burst disks ( leaking from the 2 set screws) anybody have an ideas what when wrong before I start ordering parts??

Likely the pin oring at the top of the tank. Take the bonnet off and check? But would a use a general leak like that.

It sounds like the internal regulator o-rings. The urethane o-rings perish after a few years.

You can get a rebuild kit for these.

Just make sure the tank is empty before removing the bonnet.
