I installed the fuel vent lines in to the fuselage today. What a challenge! Bending them wasn't too big of a deal but getting them in to the gear towers was a bit of a pain. It meant flexing the lines around. I got them installed though. Once they were installed I attached the fittings and then bent the lines forward just a bit where they exit the bottom of the fuselage. Then I cut them perpendicular to the airflow.
