FX Fx Impact M3

So, got the m3 to shoot and the air had all leaked down. Refilled to find a leak at the adjustment for the power plenum pressure and no pressure at the third reg. Replaced o rings in the pressure adjustment for the plenum reg, refilled with air and now there’s no leak but still no pressure at the power plenum reg.

Check for dirt on the port of the inlet valve.
There´s a really minescule little hole there. Check that vs a light.

Did you adjust the regulator after you rebuilt it? Back it off 1/2 a turn and see if the pressure starts to go up. Not sure what your experience is with pcp airguns since you are new here. If pcp’s are new to you get on the internet and download a FX M3 manual.

Make sure the plenum gage isn't over tightened. If it gets over tighten it won't let the pressure get to the gauge.

I did back it off after I replaced it, surely there’s just some dirt or something interfering some how. Crazy thing is it was working fine last time i shot it.
