I hate top filling my kayfuns. Since i put a glass tank on, i am forced to top fill.... Pita, but i put a wide rubber band over the air intake hole prior to top removal. It does help, since i have large hands.
oh really? Im thinking of getting a glass kit too and didnt think it would affect bottom filling. I only did top fill since Im using the metal middle tank piece for my nano kit and thought id be able to better judge how much im filling in.
