Question on Gas Gauge Window

[jchochole]

Hey Guys,
My original gauge was in bad shape and so added a repop unit, my question is about the center window part, does that threaded window center section need to be super tight and/or sealed with Permatex? Mine spins in and out quite easily and naturally I don't want gas leaks.

Thanks and sorry for the noob question,
Jim

I just used permatex gasket sealer on the two cork pieces. Then tighten until tight, let cure for a bit and fill.

I use cork gaskets and no sealer. Just be sure to use the right tool to make sure the inner and outer nuts are tight. Use the brass rings of course.

I do the same as Tom... Cork & no sealer..
The repo gas gauge nuts have been a problem lately screwing together... The thread pitch is wrong

[jchochole]

I used the cork and brass washers, but added gas-resistant sealer. My only questionable spot was when tightening outer ring, the inner ring kept wanting to turn allowing the whole thing to spin.

Didn't know if I should go back and seal that inner star ring as well?

Thanks,
Jim

As mentioned the threads are an issue On the repo
Send them back and use the old nuts

Once the inner nut is tight I use the tool to hold it from turning while I tighten the outer nut.

A side question, is the glass with a magnifying bubble in the middle factory or aftermarket. If it was stock when did they use them.

Used from the start through early 1929.

Per the "Restoration Guidelines & Judging Standards" page 6-5, 2011 revisions:
"The early 1928 gas gauge had a vertical oval opening with a flat lens and was used through May 1928. In April 1928 the gas gauge was redesigned from a nickel plated steel casting to an aluminum die casting, nickel plated on the exposed face. Nickel plating was not used after June 1928. The aluminum frame gauges had a magnifying glass lens with a horizontal oval opening through mid 1929."
