If you've ever disassembled an FX Cyclone you'll see in the photograph that the entire air tube must be removed, as the cut out at the top of stock is smaller than the diameter of the tube. If you look closely, you'll see the round brass part won't let the action lift high enough to clear the gauge, hence the action can't come out! !@#$!@$#!@$!
What to do. BTW, you can't see this, unless you remove the barrel. At least I didn't have a scope mounted, so it was no big deal (only two allen screws)
This picture was taken before the one above. It is what you see when you remove the barrel. Note the nut. I attempted to remove the airtube using that as a wrench point (no luck, seeing a pattern here?). I remove the nut, and the needle valve (some call it a food vavle) which prevents air leaking out of the tube when you remove it from the action.
I removed the nut and the foot valve (needle valve) with a 9/16" Brake line 6-point wrench. Now to get off the large brass piece.
I had a thick piece of Stainless Steel welding rod that I bent into an L-shape. (seen at the bottom of the second picture). I had to shorten the shorter side, but I used it in the opening (just barely visible) to turn it. If the leg is too long, you can't remove it when its against the stock. If it is too short, it won't reach the other side of the brass fitting and not turn the fitting. Success, the brass piece finally came out!!!!
I cleaned up the valve and seat, siliconed the o-ring and set it aside) (forgot to take pix, sorry)
I went to the other side of the airtube, and this is where the air was escaping (LOUDLY). It was a bit loose too. I cleaned up the needle and the seat, lubed the o-ring. I then re-assembled both ends.
Note: That Stainless Steel welding rod came in handy! You can use a round object in the fill probe area to hold the one end of the aritube, but the other end is trickier. I inserted the welding rod in this hole located at the receiver side of the air tube. This allows you to get a good grip on it without marring the surface. (I got another 1/4 to 1/2 a turn from handtight on it, so it has to help seal it better)
It now holds air. I'm giving it a 2-day leak test and will let you know how it turns out.
I hope that helps out somebody else someday.
