Fuel gauge big nut
 

Anyone know the socket size required to fit the outer nut?

The alloy gauge tool is useless...

Use the flat steel laser cut tool . It is cut to fit the nut .It is available from all the parts sellers . It works a treat . It has a slight offset on it so you can tap it with a small hammer .

John in cloudy Suffolk County England , rain tomorrow for IMAFD Day !!! . Will have to use my weather proof 31 CCPU .

Updraft,
Everyone should buy the STEEL tool set, The ALUJIMUM ones fit loose, ALUJIMUM must shrink, when cast???
A friend glued a thin strip from a tin can, half around the inside & it fit "pretty" good. He said, "I converted it from S.A.E. to METRIC"--LOL
Minervas' was stuck BAD! I put a "ding" on one of the flats with a centre punch & tapped it loose, with a HAMMER! It was full of WHITE stuff??? Did "they" ever make WHITE Loctite:D Brushed it clean with a brass bristled brush & it screwed in EASY:)

I agree with John that the steel tool is better, but for right now I would use a Dremel and clean up the inside edges of the aluminum wrench until it fits just right. Then it will be a good tool.

X2 what Don just said. I only have the aluminum wrench set.

Re: Fuel gauge big nut
 

Looks like sockets have a different number of "corners" so that's out.

Not sure how you could alter the alloy one. It is way too big.

Be interested to know if someone has bought one recently and got it to work.

Updraft,
Mine worked OK after I "tapped" it loose. It worked OK to tighten it. They don't have to be TOO tight.
BOTH my cars had some EARLY re-pro's & the PLASTIC windows MELTED & turned BROWN! With an inexpensive "kit" & the better float, I saved them.

The aluminum box wrench is just a little too tight, so using a Dremel with a small diameter grinder, just go around the inside and remove just a thin layer, then try it again. You might also try a file to remove just enough for a better fit.

Re: Fuel gauge big nut
 

The laser cut tool is a very snug fit and if used correctly will not damage plating on the nut,never has for me . I do have the aluminum one as well and even after dressing it to fit it is not as precise IMHO .

John in sunny Suffolk County England had a grand day out
the rain held off in my flying 31 de luxe coupe "Penny" from Nebraska on IMAFD.

Tom, I think Updraught is saying the wrench is too big to grab the nut.
Maybe some saran wrap over an old nut and JB weld on the wrench , press together and fill in the wrench to the correct size

Re: Fuel gauge big nut
 

The one I bought recently simply took the corners off the nut trying to get it off. Like, real quick.

It was from the local supplier here which, as far as I know, is Snyders. It'll go in the bin with the clutch disc.

Re: Fuel gauge big nut
 

Thanks, I see that now. I'd never seen one too loose on the outer nut. The few I've worked with were a bit too tight to fit all the way down.

Before you toss the wrench, check it on a couple other gas gauge nuts.

I use Metrich tools, I have a 62 piece set that I carry with me always! Metrinch grips the flats between the corners of nuts. Rounded off nuts no problems! Google Metrinch and see their design, maybe you can alter your wrench like Metrich and get that nut loose. On the web sight, they have up to 1&3/8 single wrenches, kind of pricy but they work when others will not! Hoping this helps!

Re: Fuel gauge big nut
 

At the last swap meet I looked at a set of Metwrench to see how one socket can properly grip both sizes. Many sockets now have the 6 or 12 sides curved inward to grab the side of the nut without touching the points of the nut, so they don't round them off. On the metwrench 6 of the points come inward more than the other six, so when you slip the socket on nut be sure the tighter size is slipped down over the nut.

Bill, Years ago, we used to use "White Lead" to seal threads. it worked like Neverseize. The stuff is illegal now (I think). If it had sting in it, it would have been "Oakum" that early plumbers used on threaded pipe joints. It was no more than lead pigment without all the oils. It dries out and gets crumbly over time. Try soaking it in linseed oil. Actually any rust loosener should work on it.

Another method would to "stake" the aluminum with a center punch or a small chisel.
