Fuel Level Sensor tank (above header tank) gas leak
I've found a small gas leak in the fuel level sensor tank. It appears to be the bottom most connection. I think it's the fitting and not the hose (I replaced the host about 3hr engine time ago during annual). Wondering if anyone else has had this issue. Also wondering if the gasket dressing in the image attached is the right one to re-seal it? Once removed what's the best way to clean off the threads?

I wouldn't use that. If you are talking about the threaded connection, I recommend PFTE thread sealant, ensure that you use one that is not affected by petroleum products.
Permatex does have that product.

Interesting... When I asked much the same question about fittings in my header tank, I was advised to use exactly that product. I have since become aware of a product called Gasoila that contains PTFE. I'd be interested to hear others' recommendations on this topic.

This is the stuff I've used, and it works good. Even good on an old plastic header tank. JImChuk

This is what's on there now and didn't seem to work. Or maybe I just applied it badly. Probably the latter since all other areas are fine.

I use loctite 567 thread sealant.

Good morning,
The builder's manual for our S7 recommended Permatex 9AR for fuel fittings (tanks, header, etc), which most recently has been sold as Permatex 80938 (both called "Tack and Seal).
It is a white, non hardening compound. All of the fittings I used this on from the start have remained leakproof; and, if necessary to unscrew them, it is still somewhat soft (non hardening) and easy to take apart.
I think Aircraft Spruce still finds it on a search for "9AR", although I have purchased it at my local auto parts store.

I found the 9AR to be unobtainable. Contacted Kitfox who sold me that 85420 stuff
Re: Fuel Level Sensor tank (above header tank) gas leak
Permatex Tack and Seal works great, in the end there's a lot of sealants that work well
This works well for threaded fittings:

Agreed - EZ turn is good stuff.
