Ye Olde Dancing Fuel Gauge
 

I've read all the previous posts about dancing fuel gauges...the ones that go nutso after the level falls below 1/2 tank. Light works fine and gauge works fine above 1/2.

Right now my fuel level is very low, the light is on and the float is sitting at the bottom of the tube, not moving. But the gauge still bounces around.

I swapped out my sending unit with a known good unit and it made absolutely no difference at all.

Did anyone ever figure this out??

Oh yes, 1991 300E.
