I finished installing the last four of the Left Tank Ribs. I guess I broke my rule of two per day. It became apparent that the ProSeal mess on the outside of the end ribs was totally unnecessary. The Proseal on the inside of these ribs is all that is needed. The extra ProSeal does not hurt... just looks ugly. Oh well... live and learn. I temporarily mounted the Access Cover Plate with the Fuel Sender in prep to start on the interior fuel and vent lines.
