I purchased the HUMA regulator from Tony at TalonTunes set at 100 bar. When I installed the regulator and tried to fill the Taipan with it cocked, it would not fill past ~95 bar. I thought I was having trouble with my compressor at first but when I disconnected the compressor, the rifle lost what little pressure it had in it quickly. There were no instructions with the regulator and I couldn't find any online. Is there some trick to this install? I watched the only video I could find and did exactly what he did, I thought. I noticed when I put the HUMA reg in that it slid in easier than the Taipan reg. I'm at a loss once again. If you have experience with this same situation, please share it. Thanks.

If it's the correct reg with the correct O rings, you should have felt similar resistance when inserting it.

It was noticeably easier to insert and when I took it back out, I tapped the tube on a thick layer of towels until it slid close enough to the opening that I could put a machine screw in the end and remove it.

but a deaf man can see bubbles!!! take the stock off and look for the vent hole for the reg. it is right were the reg sits, it vents the area between the regs outside o-rings, my money thinks you got a cut o-ring. a little soap and water on a washrag wiping over the hole will show bubbles

If the reg is installed backwards it would a big problem, it would hold air in the bottle side and not release it to the plenum, then you have to unscrew the manometer to vent it out

so lets get some ABSOLUTES HERE ?

It does not fill past 95 bar because air being put in ... is exiting just as quickly ? ( Tho you can't hear it ) ?

Or it just stops filling period at 95 bar ?

Unless you have a run away leak somewhere that you would hear as well feel the air squirting out someplace ....
Not filling above 95 bar has nothing to do with a regulator.

His Taipan regulator could not be set as low as he wants and his ES and std deviation are high. He is not trying to replace a known good Taipan reg, he is trying to replace one that was not doing what he wanted the gun to do (shoot lighter pellets at reasonable speed) nor did it do what it did (shoot heavier pellets) well. Others report the minimum setting of the Taipan is about 110 bar. It's his second 177 Taipan although he has other Taipans which shoot well in other calibers.

It would fill to about 95-100 bar then no more. When I took it off of the compressor, it would lose all pressure within a few minutes. These pictures may explain the problem. This is how they line up inside the air tank. Note the vent hole on the air tank with respect to the reg. As I said, there are no instructions for the HUMA and a Taipan 177. The first pic is with the Taipan reg and second is with the HUMA. It would appear to me that the spacer on the HUMA should be about .7 inches long instead of 1.2 inches long.

I think this could be a clue... I don't think there is any place to screw a machine screw into a Huma reg on the downstream side. If you screwed a machine screw into the little brass nub, the regulator was installed backwards.
