Continuing on - we're getting the inboard rib in, and the tank attach bracket. Same process. Proseal everywhere. Just before this we had installed the tank vent line through the snap bushings in the ribs. When the end rib goes in, you attach the vent to the bulkhead fitting in the end rib. We added a blob of proseal after properly torquing the nut just to make sure it wasn't going anywhere.Then just the final rivets for the end rib.

Then we go through the process of figuring out the correct bends for the fuel sender. The one I ordered is basically a 1/4" tube that you bend to fit wherever you want. there's an isolated conductor inside the tube and that's how it takes it's measurement. I figured that i could get the measuring tube to go diagonally through two bays of the tank, so that we could get the best fuel measurement. The difficulty is that the sender tube cannot make contact with any part of the tank internally. The sender that i bought has the first 6 inches bendable, then the rest needs to be straight. Since it installs in the side of the tank, i have it bent up, then down diagonally. The fitting process was pretty nerve racking, because it took two months to get the senders, and I didn't want to screw them up by over-bending, etc.

So first i bent a coat hanger bent to fit. Then the sender. It was scary, but I think it came out excellent. Now I need to remove it to test. I really want to make sure it works before I install it permanently...

Here's a view from the side. The flange for the sender has the little calibration screws on it, and obviously, the wiring.
