96 ss tank. The big nut is metal, but either there is no o ring or its worn out. Cant remember. A shot in the dark but anyone know the size of o ring that goes on the sender?
Could I use Permatex blue (rated for fuel) or should I just get a new ring?

Get the rubber gasket ring for sure. Check everything under there for a leak.. Better be safe. Imagine a major fuel leak onto the rear cylinder head or exhaust in Summer, right under your balls. :o

Sometimes they leak through the potting that seals the wires.

Clean it up and spray some aerosol powder to make sure it's the o-ring.

Some have had success redoing the epoxy.

If it were me I'd just replace it. The possibility of a leak in that area is not worth saving money IMO.

Nah, it did not ignite from heat just smells bad and scary.

Upon closer inspection it is coming from around the nut and not the wires. Turns out I had an extra sender so Im gonna try the o-ring from that one.
Maybe add some permatex blue for extra assurance.

I always add some Hylomar when installing those...might be similar to the Permatex Blue.

It lubricates the o-ring as much as seals it.

I learned about lubing o-rings from a buddy that was a submariner.

With the Summers we have here, the risk of a fire from fuel on the rear cylinder/exhaust area is a real possibilty. I wouldnt put my balls on the line for it.

Benzin fires up on ~200 C.
You spend summers in hell? :o :o
But exhaust pipe gets much hotter than 200, watch out for it  [roll]

I've seen 50C [evil]. The glue melted out of my helmet on Black Saturday.

In speaking of lubing stuff, do valve cover gaskets (the metal kind) receive any lubricant/sealant or just a clean dry install?

If they're the "rubber" coated metal ones, all surfaces clean and dry for install.
