Here are the two that I bought.
https://www.fasttech.com/products/1690303 I don't have anything like this and don't have any idea what the problem could be. My Evods don't have the removable drip tip.
https://www.fasttech.com/products/1442205 This doesn't have one of the gaskets on the base that mine does, but otherwise looks the same. Have you checked the gaskets to see if they are goobered up or missing? The gurgle could be that there's not enough wick material in there to fill that space allowing too much liquid in, or the gasket on the bottom of the coil if missing or messed up. If you don't have enough wick to fill the hole, you could 'fluff' the wick a bit moving it up some to fill the hole. Have you tried replacement coils?
The first one leaked up into the mouthpiece where the drip tip goes in but didn't leak much thru the bottom. The second one leaked into the atty connector pretty consistently and both gurgled.
