I need some help with filling up a cartomizer tank. A few weeks back I ordered 2 Texas Tuff tanks from Vapedudes, and i'm just now getting around to using them. I've never used a carto tank before and I thought these would be easy to fill because they have the side screw I can pop right out and use a syringe to fill with. I just watched the the vid on Vapedudes about how to fill a Texas Tuff tank and what i'm unsure about is how to deal with the carto. The vid recommends that I put about 10 drops into the threading part of the carto to "prime" it. I assumed I would just go ahead and fill up the carto with juice then fill up the rest of the tank but the vid is telling me otherwise. Now i'm not sure what to do. I would appreciate if someone with experience would please let me know the best way to fill my tank, thanks.
