It just presses up to the airbox. I had removed the seat-part of the snorkel previously and put it back when i installed theramair just because i didn't want to throw it away and not clutter up the house. I already have all the other plumbing laying around.
When i ran the stock seat it only attached in rear on fender, the screw attachments under seat were not used, front goes under tank lip, its not coming off
