I tightened the nut on the connection, but don't really understand why there would be gas in the vent line.  I also noticed that when I opened the fuel cap, there was a hiss like a suction.  I feel that either the vent line, which seems open when I blow air through it from the cannister attachment or the carb bowls (ZS 175s) may be too full and there is a vacuum that is pulling fuel out of the bowls.  My TR6 does run rich.  I don't understand why there would be a vacuum in the tank.  Also, I noticed a bit of oil around the oil fill cap which I have never seen before.  I checked the oil and the level seems correct.  I thought I smelled a bit of gas in it, but that may have been a bit of imagination on my part.  Any suggestions would be appreciated.
