Tuning Classic Leshiy slow leak with Huma

[Romy]

Hi. Just wanted to see if anyone might know how to fix this.

My leshiy got a 5 bar a minute or so leak when using a huma regulator, standard not a 12ft/lb one.

It worked fine for years but eventually I found it with zero pressure.

I replaced 5x2.5 gauge ring ,18x3 ring between back plug and reservoir, Huma regulator ring 19x2.5 . With this there is slow 5 bar a minute or so leak still.

When I switch back to stock regulator the leak goes away. 

Could there be anything wrong with Huma regulator besides that o-ring that I already replaced?

Could it possibly be a ring on the Huma’s plenum the screws into forward plug?

Any input appreciated.

Do you have an o-ring between the reg and plenum body?

I don’t think so… I only see two rings on huma reg kit, one on the regulator itself and one before plenum threads where it screws to the front plug.

If it is leaking, the air has to go somewhere. Check with soapy water etc.

There is an oring between plenum and regulator, not on the side but on the surface where reg touches the plenum.
