The only RTV's that are gasoline resistant are flurosilicones. These are not generally available in the automotive marketplace and are very expensive.

James,

Ready for sticker shock for flurosilicone?

$127 for a 3 oz tube. Ouch.

I've used EZ Turn fuel resistant lubricant/sealant with good success on all my fuel fittings. https://www.aircraftspruce.com/catal...ezturnlube.php
