Tuning First mod attempt didn’t go well...

I decided to put a plenum on my Dreamline. Followed the Video, degassed, installed, and went to refill. There was a air leak at the fill port, noticed the o-rings nearest the outlet was pinched. Got the fill probe out, re-set the o-ring and went to refill. Pressure got to 100 bar and it blew the fill probe out! I always secure the whip mid-line so just a big blast of air. No damage, nothing hurt except lost the o-ring. So I need a new o-ring and also what did I do wrong re-filling the gun. What size o-ring goes on the fill probe? Thanks all...
 
Ok, replaced the o-ring on the fill probe. Started filling and had air leaking around fill port. Completely disassembled air tube, lubed Orings, checked fill port O-Ring, put regulator in, installed plenum, put air tube back on . Filled gun to 230 bar. Pulled fill probe, took off ear protection...air leaking from regulator adjustment port, regulator looks to have moved in air tube. I did turn regulator screw clockwise several turns before filling. Any idea why it’s now leaking around regulator? Help!!!

I think I found the problem. I line up the wrong screw on the regulator in the adjustment port. I going to refill and report back in a few!
