The caulk will not poison the gasoline (noticeably) but the gas WILL eat
the silicone. If you read the tube of Form-A-Gasket (RTV Blue's what I
use) it says not for applications where gasket is immersed in gasoline.
You can get a product called Seal-All that is unaffected by gasoline. I
don't know if it's safe for plastics though.
Might also be able to wrap the float with something like a closed-cell
foam. Not being a foam expert, I'm not sure what kind. You're looking
for something that can withstand constant immersion in a solvent.
