So, an awesome carbon fiber drip tip came in the mail today, and as I was going to put it on my Subtank Nano, I noticed that the base of the tip is just a little bit too tall. There is about a 2mm gap between the bottom of the tip and the top of the tank. Is there any way to fix this? Would I be able to sand down the base of the tip a bit to get it to go in all the way?
