First I tried Aviation Form-a-Gasket Sealant - lasted ~1 month then started seeping.
Second I tried Permatex #1 - lasted ~6 months and now it's seeping again.
I'm using the rubber gasket that came with the new sender. Is there some other gasket material that'll work better? Is there a better gasket sealer?
Tanks!

It's odd however,my 52 uses a rubber gasket,and I didn't use sealant.No leaks.Humm Now you have me worried  | | | | | Joined: Jun 2007 Posts: 17 New Guy | | New Guy Joined: Jun 2007 Posts: 17 | Thanks! I'll try that. Maybe I should've not used any sealant in the first place. | | | | | Joined: Sep 2007 Posts: 59 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2007 Posts: 59 | I had similiar problems in my 54. I used seal-all and it has held for the past year. Also make sure your gas cap is venting. When your gas tank gets warm it builds up pressure and the pressure finds the weakest link. Which sounds like your gasket. Good luck. Hope this helps.

It's NOT the same stuff as the 3D brush-on liquid- - - -Super 300 is almost black while 3D is brown. A thin layer of Super 300, and a cork gasket if you can find or make one, should solve your problem. Most parts stores have sheet cork gasket material, and you can use your rubber gasket as a template to cut a cork one out.
