After getting some more 5052 tubing, I made the new(est) aux fuel vent line, and then pressure tested the vents, to make sure there were no leaks. Because there are several tubing connections in the leading edge where access is very difficult, I wanted to make sure there were no leaks prior to closing the wings. After pressure testing to a full balloon, I sprayed soapy water on the fittings, and in fact found some slight leaks which went away with further tightening. If I develop leaks later on, I'll need to make additional access panels to fix them, so this was a beneficial step, I think. I'm going to pressure test the right wing, after I finish this one.
