Default Do you use gasket sealer on cork gas gauge gaskets ?

What’s the consensus on this ?

Many thanks - JIm

I don't, just make sure everything is clean and feel for any burrs.

No sealant !! Cork gaskets and make sure all ridges on tank side and back of gauge are clean and free of old gaskets and debris
Tighten well. Should be fine .

I used a light smear of Hylomar Blue on one 10 years ago and still tight after 10 years of E10. Not even a hint of smell.

THIS STUFF from Permatex is relatively new, easier to find, and good with ethanol.

The trouble with the cork gaskets is the cork sheet stock manufacturers do not all use the same binders and there is no back-trace to specs on small demand stuff like Model A gaskets. Some cork sheet is very E10 resistant, some types fall apart. I made sure I also coated the inside edges of the gasket with the Hylomar blue for that reason, but again, that was 10 years ago.

I agree with Mike K, Hylomar Blue is best. They have an original Universal Blue formula and then the have the AF (advanced Formula). I prefer the Advanced Formula myself. (I have used both.)

I've never thought of using Hylomar Blue on those gaskets but I have used it on the head gasket. Even those crappy silicone gaskets are OK with a sealer like that even though the instructions say to not use a sealant.
I have used Permatex #3 on the fuel gauge gaskets.

Cork gas gauge gaskets work best dry, and used with brass slip washers. The brass slip washers used with them allow them to keep their shape and not distort. In my 2 year old Snyder's catalog they are A-9331.

Thanks to all for your responses. Where does the brass slip washer go in the assembly order ?

Thanks - Jim

Between the gauge and the big nut. (Sorry, senior moment.)

Why not use neoprene gaskets instead of cork? Probably more resistant to alcohol in our gasoline today.

the slip washers goes between the big nut and the gauge, they are there to keep the gauge from turning when you tighten the big nut,

If grease is a sealer that's what I used, 15 years ago. The cork float disappeared a couple years ago, the gauge came apart easily, replaced the float, reinstalled with the old gaskets and some grease, no runs, drips or errors! I did buy some quailty steel tools, the aluminum tools are junk!

As above, Maple Syrup has been mentioned many times over the years.
