"I started working on the plumbing for the right main tank. If I had to do it again I would leave a little more room on the inboard side of the main tanks. I centered them and it's a little tight for the fittings. The 45 degree fitting at the main tank aft is the most bothersome. I installed the tank to mark for the holes in the rib then remove the tank to drill and when I put the tank back in it seems like it moved. I can't seem to get the tanks to fit in the same spot twice. So after a little work I finally got it to fit. I must have removed and replaced the tank about 6 times though. Once the individual lines were made I had to remove the main tank one more time to fit them into place.
Next I plumbed the aux tank line to the main tank sight gauge line. I realized that I didn't plumb the left aux tank to main tank so I'm not quite done on the left wing yet."
