Are there any grades of RTV silicone that are resistant to gasoline? I did a search on this forum and came up with nothing.

Yes there are fuel resistant grades, but you won't get them from your local auto supplies discount house.

Try Dow Chemicals (Dow Corning ?) GE silicones or an aircraft maintenance supplies house.

Most RTV silicones swell disturbingly when fully immersed for lengthy periods in gasoline. There are available some fluorosilicone elastomers that have better resistance. Contact one of the manufacturers Pat Primmer suggests.
