I have a orange tank vent in a 066 that I have a question on. Gas leaks thru it and I was wondering if it is differen sizes on the little orange rubber vents because I have one in a 026 also that looks like it’s the same size.. but the one in the 066 looks to be a little loose in the hole.. I guess I can get another one and try it too see if it ps any tighter but I was just wondering if it was different sizes..
