Sumatra filling issue

Hey Guys,
I fill my Sumatra from a small carbon fiber bottle. Today, when I went to fill it, air was leaking from my quick connect. Tried it on the hand pump and still leaking. Gun is holding air just fine, just slow to fill while the air is escaping from my quick connect. It isn't the female end as I charge all my air rifles with that tank. Could it be the check valve or the male quick connect on the gun? The male quick connect looks fine.
Again, it takes air under high pressure, just very slowly and is leaking the whole time while filling. Any advice would be appreciated.
Thanks

Sounds like the o-ring that your male foster fitting sits on needs to be replaced. I had an issue with the check valve with my Sumatra and all the air would escape. If yours will take on and hold air, it sounds like theres just a little air escaping from around the male foster fitting due to a bad seal.

I the female connector damaged??
In some cases, also Sam Yangs out of the box, that o-ring leakes while filling the air rifle.
In the karton box of the Sumatra should be a little plastic bag with a spare o-ring for the Foster male connector. Changing the o-ring does not always solve that problem.
I uncrewed the male connector and had put a second o-ring with O.D. = 10,65mm x 1,85mm behind the small ring that is already in place. Don't remove the original one, leave it in place. (Sorry, I had no pictures made.)
It looks very unprofessional but in my cases it did always his job.
