Today I got on with the fuel tanks. I made a gentle upward bend in the vent tubes in both tanks so that the end of the vent would be above the fuel level even after filling the tanks. I then sealed one tank skin and it's rib ends, I put dobs of sealer at each corner and then placed the rear baffle into position. I clecoed the rear baffle to the tank ribs and skin, and then coated the AD 41 H rivets with sealer and riveted just these rivets.
