U-force tank L leaking

Hi! Last month I boughy Voopoo Drag 4 kit with uforce L tank. It was smooth experience for 1 month, but from last week I have problem with leaking in this tank.

Liquid after few minutes is flowing to bottom of tank (see picture) and when I inhale I feel bubles of liquid, probably if I would inhale stronger I would inhale liquid to my mouth.

I changed coil for new one and 2 orings, for 12 hours it was fine, than again it is leaking..

Any ideas how to fix it?
