So dropped a huma reg into my huntsman revere, since the unregged one was way cheaper than the regged one even after buying the reg. Problem is the vent hole is venting out the end of the air reservoir while pumping. Not many orings to check in the reg. I pulled it back out and the air tube holds like a champ again. Any ideas?
Tuning Added a Huma reg to my Daystate Hunts

Saw a video (youtube) of an install on a Regal XL, not a Revere awhile back but I would venture to call AoA's service department as they are THE DAYSTATE service center in the US. Awesome carbines! Hope you get it up and running with Huma soon!

I went with the directions from huma and there is a whopping 5 steps. Took the orings off the receiver before reinstalling the airtube so not sure which oring is not doing its job on the regulator.

Not to be insulting, but are you sure you are installing it in the correct orientation, adjustment screw on the high pressure side?

Yup screw toward the fill fitting. I am sure some will say that since I am using a hand pump that it needs a quick burst of air to seal against the receiver. It really is an idiot proof installation as they provide pictures and written instruction.

Since it fills properly without the reg, that seems to indicate a damaged or ill fitting O ring on the reg. Interesting, please post the resolution.

I may pull the piston and see if the oring on there is not sealing to keep the air on the upstream side.

The oring on the very back of the Huma reg that seals against the receiver must be perfectly sealed to prevent air from coming out of the "thread gap." I just did this on my .177 and it leaked when I went to fill it. I left the fill valve on and moved the cylinder around a bit (threads are loose fitting) and it sealed up. Once there is enough pressure in the tube, it will create a strong seal.
If you're using a hand pump for the initial "seating fill," you may struggle unless everything is perfectly lined up.

I had Huntsman lose pressure from storage, and pumping resulted in air escaping through the barrel. I only have a hand pump. I reseated the valve by cocking the hammer and dropping about a foot butt first on the floor. Sealed and filled right up.

I have some old paintball bottles sitting around that I could probably give it a burst of air to seal the reg against the receiver.

Update: so filled up a paintball tank to try and give it a buratbof air tobseat the reg against the bottom of the air tube. It was still leaking slightly once all aired up. I fired a few groups just to see if that would help. Reg is at 130 bar

Super consistant over 5 shot groups. I am just hoping that it sealed itself while testing. Only time will tell.

Nope still leaking. Even pulled the piston to check the inside orings. All look good. Added floss under the outer orings to tighten the seal, no luck. Pulled the reg and sticking with unregged for now.
