(I think) I'm getting ready to start the engine and one of my last remaining tasks is to flush the tanks and install the fuel senders. 



What have most of you used to seal the senders when you installed them, and how well has it worked?  I'd prefer not to pro-deal them in and I'm wondering is something like Permatex #2 form-a-gasket might be a good choice. 



Just wondering how well it has performed and especially how well it has performed in cold weather when sealants like that tend to shrink a bit allowing the opportunity for leaks to occur in cold weather and disappear in warmer weather. 



Thanks,

Phil

Fuel-Lube in my 6A.

Sealed great and wasn't a mess when the sender failed.....

Sorry.....pro-seal.  No problems, but I know that is not what you want to

hear.

We usually just use the rubber gasket that comes with the sender.

Gross over kill  I don't know if they are readily available, but rubber gaskets work well. That is what the senders in my Mooney tanks use. Everything else is pro-sealed but not the sending unit.

I installed mine with the rubber gasket that comes with the sender. Put a little fuel lube on the gasket and the screws, but am not sure that is even necessary. 7 years and 800 hours with no leaks. During this time, I have removed each side once to replace the sender and the right side another time chasing a grounding problem. Very easy job.

I believe the secret is to go easy when tightening the screws. Don't over tighten them, and tighten them evenly. The senders are made to be installed with the rubber gasket.

I used the rubber seal with some fuel lube - no problems after four years.

Thanks for all the info.  I'll just slather the rubber gaskets up with EZ Turn and give them shot.



Thanks again,

Phil

You have to be careful with EZ Turn and not use too much. otherwise, you 

will find EZ Turn blobs potentially clogging your fuel lines and filters.

I used a viton gasket and screws with built-in viton orings. McMaster has them. I can get you part numbers if you want to go with that setup.

A friend of mine uses these senders on boats he builds and he says the original rubber gaskets are junk.
