The wicking is fine i have that down i just cant stop it from running out of the AFC when i fill it and i don't know why after a tank or two after new wicking the only thing i get is hot e-juice and no vapor
Its your wicking, juice is flooding the deck. When the tank gets flooded, you'll get hot juice spitting back at you because it can't vaporize the amount of juice on your wick/coil.
When wicked properly you should be able to top fill with little to no flooding. Sometimes if I don't do it well enough I'll get slight flooding after a refill, but usually after a vape or two it has resolved itself.
If its not your wicking, it could be an o-ring/seal that isn't making a proper seal, and the tank would lose its vacuum, flood the tank, and cause the issues you're describing.
