Fabricated the external fuel vent fittings from -4 bulkhead unions. Turned the lower end down by lightly chucking them up in my drill press and then eliminating the threads with a vixen file. Cut the ends to a 45* angle per print with my band saw.

Tons of people on VAF talk about how awful these vent lines are, so I did a google search and found a video by Karetaker Aero than had some good tips for where to start with them etc. It's worth checking out.

CAUTION- the -8 screws that go into the lowest adel clamp on the fwd end of the run need to be shortened or they will hit the skin if you snug them down. I screwed a fiber lock nut down on a couple of washers and then ground them down to the end of the nut on my belt sander and that was about the right length, with just a thread or two showing through the nut plate after installation.

Other than that, no drama, just lots of off & on to eyeball where the bends should be.

These are not torqued yet, because I haven't fabricated bug screens to go on the front of the external fittings.
