FX FX M3 power plenum leaks/drains through 1st reg

[rc4fun]

First off if you are not helping and hate FX just move on..
My M3 with PP upgrade started leaking fast, OK no big deal I'll replace some O rings and be done. Well the first thing I notice is that the plenum empties through the front reg when the bottle is removed. WHAT? I changed the front reg (new) still the same. Changed the 2nd reg (new), no change. Changed the PP O rings and I think every other O ring including the 2nd stage one that is buried.
Anyone have an idea what I am missing.
Thanks much. Kerry

Yeah. No bottle it will do that depending on the settings. Nothing to worry about. I prefer mine does that instead of having to bleed screw it down.

Valve seal and the oring out the back of the power block for the valve rod should be checked iirc if you could point out exactly where your plenum leak is in a Pic I may be of more use.
