I recently added a power plenum to my fx dreamline classic. While the gun was empty I decided to up the reg to 150 bar. I filled my gun back up and the reg stayed at 150 bar overnight. When I shot the gun today I started with a fill pressure of 230 bar. By the time i was down to 210 bar the reg dropped to 140 bar. When it was time to refill from 160 bar back to full the reg was hovering around 100 bar. When i refilled the gun back to 230 the reg went back up to 150 bar. I am assuming one of the internal o rings is bad. I am debating if i should grab a huma reg and swap it out. Any feedback would be appreciated.
