I would avoid cork on any fuel system component, as today's fuel has enough alcohol in it to eat right through it. It will also eat into and destroy a cork float on a sending unit

Possibly so, though as I said I've had no problems with cork with the 10% EtOH gasoline. My float is also cork (uncoated), still functioning fine, and the gasket on the fuel pump sediment bowl is also cork, and no problems there either. Perhaps the problems will come down the line, though as I retired chemist I don't recall that EtOH attacks cork. But the old standard of coating the sending unit cork float with shellac should be avoided as EtOH is a solvent for shellac.
