Is there a safe way to degas a Maverick with Huma regulators?

[Bigragu]

HI Guys
I recently installed brass piston in both the amp regs of my Maverick,
i am facing a leakage issue issue , there is a leakage of air from the vent hole in the plenum cylinder (opposite side of the 2nd regulator), and as soon as i put the bottle the air leakage starts from this hole . Any advice is welcome for a fix and which which of the O rings may have been busted, thanx

You probably didn’t change out that inner o ring inside the regulators tunnel. Happens every time(leaks afterwards)

Not a good idea. Jasmlowe is correct. Remove tank, dry fire a few times,it will start to l bleed off, there is a o-ring under the gauge. You can open the 2nd reg a bit from max to release the pressure.

Too difficult to remove tank when it has air in it ! (at least for me)

The first few turns are tight but, it will come off, an alternative method is a small strap wrench from Amazon, reduces the need for hand strength. When off lube the threads with real grease or oil NO SILICON.

How about moly grease on threads?

I used some Permatex anti-seize on the threads on mine.

Good idea, for me it's a touch messy but any port in a storm.

Loosen up the reg gauge.

I have to agree with @douger. I have an FX Wildcat MK3 BT, which has a very similar build to the Maverick. I use 2 Huma's reg to get the max pressure too. In my experience, to dump the air in the plenum, the easiest way is just to loosen the reg 2 pressure gauge. You can do it safely by controlling the rate of the air you dump by managing the tension of the reg. Obviously, loosening it all the way instantly isn't good, the air might blow up the seal and you might send the gauge flying. However, you don't want to do this too often to minimise wear and tear.
