Default Float Sender - Gasket Question

The float senders I'm using came with thick rubber gaskets. Those of you with these senders who are flying your planes, did you use the gaskets or did you use tank sealant? Or both?

And how did it work out?

Thanks,
Dave

Tank sealant only - the thick rubber gaskets swell, deform, and leak....awful things....

Default Thank you Paul!

Thank you Paul!
I tried using the gasket on my first tank and did not like the results. I did not use the gasket on the second and went back and pulled it from the first. But I had a nagging question if I was right.

Thank you for the conformation,

Keith

Default Houston, do I have a problem?

I installed my float senders using the rubber gaskets AND proseal over the inside and out. The platenuts used were the regular "open" ones from Vans, but I believe I adequately coated those as well on the inside. What's the likelyhood that the rubber gasket deformation you speak of would cause my setup to leak?

Probably depends on how much pro-seal you slathered on......

In my first build, I dutifully used the gaskets. About three days after I filled the tanks for the first time, I had blue stains running out - I had not used any sealant, figuring the gaskets were there to seal things. Didn't work out that way.

I doubt there is a way to predict the likelihood of a good seal or bad one. It is probably a question of how accessible it is now versus how accessible it would be later to re-do. If you have the wings off, now would be a great time to consider changing (if you want to change). If the wings are already on, then you might as well see if it seals - fixing it will be just as painful now as later.

My opinion of course.

Paul

Default Paul is right

Yep. I, too, have verified the rubber gaskets will leak within 3 days, if not sooner. Just use proseal. Clean the tank surfance and the sender really well with Acetone or MEK.

Default Gaskets

Now I'm thinking I should remove the cork gaskets and Titeseal on the access plates and seal them with Proseal. I used them just in case I decided to add a return line. Doh!

Default

the tank building instructions now specify using ProSeal only on both the sender unit and the t- 708. throw the rubber gasket away.
