After voting early this morning, I got to work closing up the ER tank.
But first, I wanted to snag a shot of my baffle sealant beads. They look reasonable to me.

Next, let’s get the access panel in…

After getting my access panel in (with the stainless steel cap screws I bought from McMaster Carr), I installed the float sender and verified continuity from the center post to some tank structure).

After that, I went ahead and riveted on my ER Tank nutplate flange for the inter-tank access panel. 14 rivets on the top side, and 13 on the bottom.

1.0 hours. 27 rivets on the flange. This officially closes the left ER tank. Time to wait 3 days and then pressure test it.
