Today, I worked a little on the project, fabricating plumbing lines for the left main tank. These lines connect the left auxillary tank to the main. One connection is a passive draw connection, the other is the backup transfer pump connection. The smaller line is the vent line for the auxillary tank. The main tank is of course vented to the aux tank via the passive draw line. Since I've already done this once before, it went quickly.

Still need to run wiring before riveting the bottom skins.
