I installed the FX angled manometer bracket on my M3, along with a Sekhmet Gen-2 255Pro 300 bar Sekhmet High Pressure Digital Gauge. At first everything was fine and I could see the 2nd regulator pressure drop and refill after every shot on the Sekhmet digital gauge. However, after awhile the gauge just started showing a "frozen" 2nd regulator set pressure, there was no drop after a shot.
I installed a different analog gauge in the angle manometer bracket, and the same thing occurred, no pressure drop after a shot.
Reading through another thread there was a mention of FX sometimes installing a chunk of o-ring under the grub screw (to stop leaks) that is removed to install the angled manometer bracket.
So I degassed the M3 and removed the bracket and left the hole open. I slowly screwed back in the bottle with my thumb partially covering the open hole (I'd recommend using a rag or something instead of your thumb). At first there was a slow escape of air at that hole and then something came flying out and hit my thumb. I was unable to locate what actually came out of that hole, but after reassembly the 2nd reg gauge installed in the angled manometer bracket started working perfectly.
Hope this helps others that may be experiencing strange readings on gauges installed in the FX angled manometer bracket.
