Taipan veteran huma install help

https://youtu.be/R_uf_2frVYs

Are you sure you received the CORRECT REGULATOR FROM HUMA? 

Did you follow the simple step by step instructions correctly?

Can you push the Huma Reg and the spacer farther into the tube? If so, no problem.

Everything going smoothly until i try to reassemble. The air cylinder wouldnt screw in all the way. I took the regulator and plenum spacer out and the huma is taller than the stock regulator+spacer. See picture.

any ideas?

Is that the way you're putting huma into the cylinder?

If so the regulator sits on top of the plenum not the way you have it pictured.

Why do you want a Hum. The Taipan has great regulators. The Hum is a bit better but it's quite difficult to make with the Hum regulator to turn out as well as with the original Taipan regulator.

Side by side pictures look like your plenum is longer than what HUMA has pictured on their website for the Taipan Veteran.

ok .. HERE IS WHAT i'M SEEING .... As YO has shown a picture of



The HumA regs adjustment bonnet end go's forwards towards fill valve within the tube. The spacer ( Plenum ) goes in next against the BOTTOM of the regulator and then the valve assembly screws on.



You have the REG Inverted sitting INTO the plenum spacer in your photo's

It is the OVERALL LENGTH that matters .... not the spacer tube.

The Vent hole needs to still be in the same main tube location for regulator to work correctly. The BODY of the huma is shorter than OEM, so a longer tube required which is an ADDED bonus ... Larger plenum !!



Try this ... TAKE O-RINGS off the HuMa and make sure it can slide in far enough to get at an equal depth to the vent hole in the main tube.



ALSO ... if you took the filler end cap off the tube YOU MAY HAVE THE MAIN TUBE FLIPPED AROUND ... while both ends have the same threading, one end has a deeper counter bore for the regulator.

Ahhh just like a Marauder shroud...

I'm with @Erics on this one. I put one in mine too - I was seeing the exact same things that I've seen others experiencing of late here in this forum with Taipan Vets - erratic speeds. (shooting over chrony) One shot 850, next shot 830, third shot back to 855, 4th back down to 831. This fast / slow / fast / slow pattern was *very* consistent and highly repeatable - didn't seem to matter how far in or out the hammer spring was dialed. I did pull out the oem reg and turned it down just a bit based on a few videos I'd seen while looking into it. ( the FX guy - Ernest has one, and our own VetMX posted his how-to when he adjusted his ) I got tired of dinking with it and got the huma.

I put the huma in and . . . yup - *same thing* - plenum tube to long. Negative on the air tube being bass-ackwards - I double checked. Readers digest - I carefully measured to get what the overall length needed (needs) to be and just took a hack saw to the huma plenum tube and trimmed it down. ( take off a ~little~ over a 1/4" - I don't recall exactly what it was - .265 - .270'ish . . . . ) File / lightly emery cloth ( deburr it) - good to go.

Mine is stupidly consistent now no matter where I have the spring tension set at - depending on weight of ammo I'm playing with. If I dial it and it measures (for example) 864 over the chrony at first shot - the next 10 shots will all be +/- . . 4 or 5. If mid 860's not good - pellets not grouping good on target - dial it up to 885. Again - next 10 shots will all be +/- 4 or 5.

But yeah -- needing to trim that plenum tube down was irritating to say the least.
