No mystery though perhaps not quite common knowledge, cork floats will ultimately become saturated from immersion in gasoline, that's why they were coated with shellac which in the day of the "good old gasoline" was a perfect coating. However since shellac is soluble in alcohol, it's no longer a suitable coating for today's E10 gasohol. Plastic or brass floats are the answer for gasoline though the shellac-coated cork float in the crankcase that some of us have on mid-30s and earlier senior cars to read the oil level in the crankcase seems to hold up just fine.
