Maybe a dumb question, but what cork gasket are you referring to?

I ask, because I happened to install my fuel senders in my RV-10 wings over the weekend. The senders that came from Van's with the wings had a black rubber gasket.

The -7 kit came with a cork gasket to seal the float mechanism plate. I't was suggested by Van's and Synergy Air that not using the gasket was a viable option. Apparently some of the cork gaskets would fail over time.

I got rid of those rubber gaskets and just used the tank sealant. Worked fine on both tanks.

I actually ended up using the cork gasket, but coated with Permatex "Aviation Form-a-gasket" including around each screw:



No leaks through the gasket, however both tanks still leak through the capacitive plate BNC connectors. Haven't figured out how to solve that one yet.

I got rid of the whole access plate, and never cut the hole in the first place (but I have the capacitive sensors Van's used to sell...never a bit of an issue with them, knock on wood).

It can't leak if there's no hole there in the first place

Shop leak testing is a good thing, but realize the real test comes when you G 'em up with 120 lbs of gas in 'em.
