And, in an incredible coincidence,
the right main gas tank gauge that had stopped working immediately after
some avionics work (the classic "maintenance-induced failure") last fall
turned out to be the float having fallen off the sending-unit arm,
rather than a gauge problem. Who'd a thunk?

This meant draining the tank (full, of course) into 5-gallon cans,
removing 8 jillion screws, disconnecting the fuel hose (dislocate wrist,
cut forearms), disconnecting the grounding wire (dislocate wrist, curse
inventor of flat-blade screw drivers), removing the tank, fishing the
float out of the tank, removing the sending unit, blah, blah, blah.
Reinstalling it was great, too, since the very last screw would not
thread into anything, and I had to start all over...



Nice design, Mr. Piper. Beech Bonanza you take off the access port on
the top of the wing to expose the top of the bladder where sender is
located. Remove 6 or 8 more screws and sender comes out. No need for
tank to be empty, down 5-10 gallons helpful. Sender out in 5 minutes.
