Hi Jim,
I am of the same opinion as you. I have put EZ fuel lube on my
cork gaskets (both sides) and installed them. I used moderate pressure
on the screws so they should not leak. I need to get some av gas and run
some test strips to see how it is affected. It seems at this point to
reject the fuel quite nicely. So--- I am running with it that way.
Worst case, I'll have to replace the gaskets and do it bare . I can not
think about pro seal on the fittings. I did get some silicone O-Ringed
screws from McMaster Carr so the fuel would not come back up the threads
and leak that way. For the standard float level Stewart Warner senders,
I added a ground wire to the sender to be sure they would work. I think
I have it on my web site at www.websites.expercraft.com/jimn so take a
peak.

Jim, My A&P told me that he has uses EZ Turn to seal fuel tank senders on
various aircraft over many years and that it has worked good. I'm hoping he
is right because it sure is easier to work with. I used proseal on all the
other parts on the fuel tank sender and fuel line but I used the EZ Turn on
the screws and gasket. Thanks for your reply, it's great to know someone
else is trying this product. I need to add fuel and then test it over the
years for the final outcome. More to come later!

Jim

Check the RV-list archives before you go with the fuel lube and gasket
approach. I think you'll find a spotty success rate.

History shows that using Proseal with no gasket gives you the best odds of a
leak free tank. I'd go that route simply because it is a hassle to work in
the wing root are once the wings are installed, and you'll be happier
avoiding that chore down the road.

Silicone is not recommended for use with hydrocarbons (avgas or mogas)
as it swells and gets very soft. Viton, fluorosilicone, Kalrez are all
excellent when exposed to fuel. Buna-N is good and especially where it
is not immersed in gasoline is an acceptable inexpensive choice.
