I've been trying to get rid of the fuel smell I get after landing from the vent lines of the bing carburetors.

I originally had the tygon vent lines plumbed back into the larger KLN air filters but once I replace the larger filters with smaller, that was not an option. Besides, plumbing back into the filters really didn't resolve the venting problem.

I'm curious if anyone has taken the vent lines and either extended them down the side of the firewall or even "T"d them together and then routing the line down and away from any heat source. My biggest concern with altering the length of the tygon vent line is if there would be any adverse effect on the line pressures that would cause the carbs to expel additional fuel or not.

I know this has been an ongoing topic with the Rotax 912/Kitfox since the intake manifold has to be reversed to accommodate the oil tank.

I'd like to know how some of you resolved this problem and I'm willing to give it a try on my plane.
