Did not have much time today but I accomplished the following: --removed L3 thru L7 ribs from left tank skin to inspect the throw and fit of the left tank fuel sender float/arm. This is the tank where the flop fuel pickup is so the sender is maouted on the baffle. Tested throw and freedom of movement and everything was good. --cut a strip of aluminum to fabricate the left tank flop tube no-hang device as seen on the pics below. Still need to de-burr, scotchbrite, and rivet in place....this will happen later on after tank ribe have been prosealed/riveted in-place.
