Crown tank leaking thru AFC (topfill)

[Vapin4Real]

My apologies if there is another thread on this. But I am having serious issues with juice spilling out of the AFC holes when i topfill. I have only had this tank for a week and i really am enjoying the flavor/clouds. But when i fill this from the top as soon as i screw the drip tip back on juice comes out of the air holes. I have seen many people with this same problem across different sites but no clear fix (besides change the o rings, make sure the coil is tightened, squeeze the coil, its a pressure issue, etc etc). I have almost came to the conclusion that I have a faulty one since there are many that have no issues at all. Anyone care to enlighten me on what may be causing this?

The only time my crown has leaked has been when I've left the AFC open while filling. I always top fill on it. If you haven't done this already, try closing the AFC, fill and put the top cap back on, turn it upside down, and then open the AFC back up. Give it a few seconds before turning it right side up. Hopefully it's as simple as that for you.

+1 on the post above. Fill it with the airflow closed off and then open it when your done filling. This is a cause for leaking on many top airflow tanks. Also, make sure your using heavier VG juices!

I have always closed the AFC when filling but I am still getting leakage. I have found that it minimizes if i slowly screw the top cap on after ( I guess it minimizes the pressure). Also I use a 50/50 juice. I will keep toying with it and see what happens. This tank is just pure greatness tho despite the small leak. Already ordered 2 more lol.

1. Close the AFC
2. Take 5-10 dry pulls.
3. Remove top and fill quickly with a syringe.
4. Replace cap
5. Repeat step 2.
6. Open AFC and take a powered hit.
