I fabricated a two-piece anti-hangup guide to prevent the flop tube from catching on the nutplates that hold on the tank access plate. Most of the guide is attached to the access plate so that both come off together (this keeps the guide from blocking access to the interior of the tank if I ever have to get in there).
Here is the rib in place in the tank. The guide moves the pickup out an inch or so from the bottom corner of the tank, but that shouldn’t have a significant impact on the amount of unusable fuel in the tank.
I riveted a cover plate on the large hole in the second rib.
This prevents the flop tube from catching on that hole (and also helps hold fuel in this bay in knife edge flight).
