Clecoed inboard end rib in position in left tank. Screwed tank cover and fuel level sending unit into position. Checked clearance and movement of float and saw no problems. Took everything apart. Inserted bushings for fuel vent line into holes in left ribs 1-4 and then inserted vent line. Found it was a few inches too long, so it was cut down to proper length and reinserted.
Tore off more strips of painter's tape to be placed over rivet heads. Looked over all prosealed areas of right tank for any voids. Found a few that needed more Proseal. Applied Proseal to these areas. Placed Proseal on right inboard end rib/skin's joints and rib's flanges. Made about 30 grams of Proseal.
Tightened right vent line to fitting on right inboard rib.
