Guys - When I replaced the fuel sender on my '59 Rambler, I'm sure I used something gas-resistant and probably by Permatex on the gasket. If I fill my tank over half full, it sloshes around and runs down. Have you had success with a certain adhesive...or do you just replace the gasket dry?
I might put a little oil on the gasket, so the screws can go in easily, and their sealing washers won't get damaged, but no sealer. The problem with these things, is that on many cars you can't see the sender when it's installed, so you can't really see what's going on. And the leaked fuel evaporates by the time you can get it to where you can see something. My guess is there's something leaking, besides the gasket. It's time for a slow, careful inspection of the whole thing. Look for cracks, bad hose, something bent, other sources for the problem, etc. Good luck!
I use this stuff. Available at most auto part stores, plus Lowes etc. It is gasoline resistant. https://www.walmart.com/ip/Eclectic...eWbOYEKKpmwDo1xIjSQaAqQiEALw_wcB&gclsrc=aw.ds
The gasket offered for the tri five cars are mostly rubber. They need sealer. You can buy sealer that is gas resistant. Drys really fast. Has the smell of the old airplane glue we used as kids.
With today's ethanol fuel you might want to avoid rubber gaskets. They deteriorate very rapidly unless specially designed.
The one in my tank has been off at least 10 times and never replaced and doesn’t leaks. It a gray gasket material not sealed on either side. I’m assuming it’s correct for fuel as it came with the float/sender.
