FX New Huma Air second reg Gen 3 problem (FX Impact M3)

No I didn't

Should have but felt like a idiot not being able to get it to work lol

Here is what I'm thinking I did differently I followed huma directions on the install and I'm wondering if the brass piston didn't fully go into place when I put the amp back together I used a pen body to seat it in place

Did you look at the delrin valve disk for damage/scratches?

 

[Airgunmann]

I did mess one up on install but they give u 2 discs per reg

Were are able to resolve the issue?

I compared the piston length on huma and it's exactly the same as original from FX. I got extra hight pressure huma, the spring stack on those is: )()()()(

On Huma's website, the Extra High pressure starts at ~135. So if you plan on going lower than that 150 mark you need the low pressure.
