I recently rebuilded my cast iron fuel distributor, but I'm having problems keeping the thing from leaking. All the adhesives that I've tried got dissolved in a matter of weeks.
So far I tried:
-Loctite 567
-Loctite 518
-Loctite 277

Does anyone have any suggestions of good sealants?

PS: the gasoline around here has quite a lot of ethanol too, which I suspect dissolves most common adhesives.
