After many, many, many hours working on the fuel tanks I think I can finally say they are ready for inspection. Tonight I rechecked everything I could think of on the tanks. I can’t see anything obvious that needs doing. I’ve checked the aerobatic flap door, the flop tube, the anti-hangup brackets, the electricals and the caps. All looks good to me.
I need to wait for the right tank sealant to set for a few days and then water test that tank like I did the left one.
