Cork float protection

[Bruce Compton Canada]

Is there a way to be able to use cork floats with today's "gasoline"?. Has anyone tried coating them with gas tank sealer? Thanks : Bruce

Yes on the gas tank sealer. My Marvel has the cork float and did just that. It has held up for well over a year. Make sure you use the type for modern fuels.

Originally, they were covered with shellac. Alcohol is a solvent or shellac. The new gas, with alcohol, disolves the shellac and the cork will become "water-logged" and will not float any longer.

Any other suggestions other than the gas tank sealer?? Bruce

Model airplane dope worked for me.
