How to fill a DCT tank

A video I put together showing how to prime and fill a 3.5ml DCT tank. A couple of more things to mention, I would thread the cartomizer onto your battery before filling (don't fire it) to check to make sure it threads properly, and then take it off the battery and take a pull off it to make sure the airflow is not obstructed. This is a quality check, these are usually really good but nothing sucks worse then filling one up only to find out you got a bum carto. Also, when you push the carto up after filling it, put your thumb on the top of the tank so that it does not unseat and push up. If it does unseat on you, pull the carto back down, reseat the top of the tank, and then push the carto up again. If you just jam the top of the tank over the carto and reseat it, the displaced air will force a bunch of juice through the holes and juice will pour out the bottom. NOT GOOD :( Learned that the hard way! Also, when you put your drip tip on, put your thumb on the bottom so that the carto doesn't push back into the tank.
