The air would enter through a filtered cap in the valve cover. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Dec 2011 Posts: 133 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2011 Posts: 133 | I cut the down tube off of mine and found a PVC valve with a rubber gromet that came very close to that tube size. Just a little adjustment with a razor it fit perfect. I can dig up the NAPA PVC numbers if you want them.

NAPA # 2-9208. I was told that this may not be the correct valve due to it is not spring loaded and should be upright. I will have to figure out if I need a different valve.
