Guys,
I know some of you have had problems with fuel tank vents loosening and leaking, I have a trick I came up with that works like a charm with no sealing required other than locktite. Take a piece of inner tube and trim to match the base of the vent. Little hole in the center and make sure it's clear of the threads and install and your done... You will never have to screw with it again.. Just don't use the wife's bikes tube 😳.
