Hey folks. I have a brand new NX / Nos custom setup that was sealed at every fitting.

I had a couple pounds left in it when I left for vacation and left the bottle on When I came back two weeks later, it was all gone, not even enough to make a noise when purging.

I am wondering if I should be concerned, or expect this kind of behavior when leaving the bottle open for a week or two?

Do I have a leak if this is happening, or is it natural.

Thanks!
