fuel gauge in-op

[DJK]

52 Cranbrook fuel gauge read 1/2 tank, drove 12 miles then showed empty. Power to gauge OK, tank grounded OK, resistance OK, worked OK out of tank. Removed cork float, felt heavy even though it floated in gas. Went to Lowes got two Hillman 15/16" cork stoppers, installed on float arm, working OK. Love these old cars!!!

I believe, could be wrong though, that the factory cork is sealed with something.  Anyone know for sure?

Guess I'll find out!!!!

I've heard the originals were shellac and that it gets dissolved by ethanol. I put plastic floats on mine.

Looking at brass floats now to adapt to the float arm. Will also check out the plastic ones.
