I now need this since Mooney doesn't make them

Does your C have wing fuel gauges? I didn't realize we were on the STC list . . . .

My M20C did have wing sight gauges. However, I own a Mooney Bravo now!!

OK, they came in.  When I bought a new one 2 years ago, i have a vague recollection of there being ground off tabs.  

I will put one in the lathe and see if I can pull/cut it open and apart with an exacto knife.  I have $14 in each of them.  so in the terms of mistakes I have made that have cost me money this one will be cheap. Won't be the first time and won't be the last.

 

Mark, did these end up working out for you?

[ArtVandelay]

Are these the ones, would require cutting the tabs off?

If we can figure out the proper one and how to open and reseal, we would develop faces to be printed.

Hmm, I wonder what size run would be required to order a custom (OPP) gauge from them?

Make a drawing, call them on the phone and ask for a quote.

Are all the capsules the same?  With just different faces?

 

Anybody sure of the exact gauge that we have (not worried about the face)?

Yea the capsules are all exactly the same. The face is just different. I can take out my other gauge and messure

Those look like it! Just need to cut the screw tape off.

These are similar ones I bought and installed to replace the non-working one.  I had to cut off and file down the two plastic tags on the side. I haven't had any issues with it in the last 9 months I installed it. 

I did buy it off of Amazon though.

Because I am a curious sort, I called Rochester Sensors (current company name for Rochester Gauges) and spoke with Cheryl Manning who told me that Rochester doesn't sell retail and I would need to contact one of the companies on a list which she then sent me (attached). Next, I called Air Dallas and the gentleman there told me that he thought that this part was discontinued, but to be certain he would need the part number. Apparently, the 5- number on the dial is not the actual part number. The actual part number is much longer and located on the back of the dial. So, if anyone has a removed or new dial, perhaps you could look on the back and find the part number and determine if it is possible to order these.

I have a spare dial for my J model and the number is 5404S02105.

@Steve Dawson

Did you re-mark these in any way? (cut the case, re-face and re-seal, or Sharpie across the top)

The direct link to Rochester offers brutal shipping ($55 for 2 dials, which is a bit much even to support merchants directly) so I am wanting to try the Amazon route. 

 

[Steve Dawson]

Check on Amazon. It's been awhile since I bought mine but I believe they were under $35 including shipping. I didn't re-mark the face in any way since I'm still waiting for a production run of them.

I know the fuel capacity of the tanks so at the 1/2 mark it would be 19 gallons, 1/4 would be approximately 9. You could probably have waterproof round stickers engraved with the appropriate fuel levels and encompass it around the gauge until the Mooney ones are available. 

[Cayman44]

Hmmm.  

The Mooney part # for the M20J wing fuel gauge "dial" is   880024-005.   For the M20M TLS/Bravo, it is 880024-009.    Are these the same? Lasar now lists the -009 for $142 but is out of stock.   I am ready to ask one of the pdf listed dealers in Dallas that I will buy 20 or so for the M20M if that is what it takes.  Has anyone tried the Amazon part which is now $40 5323S01792 “JR and found it fits and works full swing - Empty to Full to the same stop points (Different size fuel tanks would have different float gearing so the same guage could be used just with different internal gallon labels.   If that is true, I could install it and just use my extended fuel markings I already have.  I trust the wing fuel gauges over my dash gauges.

[KSMooniac]

The different dash numbers are different markings/calibrations.

Here's a set of replacement gauges that I have for my Ovation. Its the same one, I think (Rochester 5-2100). You can see front and back with the Rochester part number on the back.

[0TreeLemur]

I bought two a couple of years ago from Maxwell.

Yours is a good idea... Extended markings to relieve the pressure to get specifically marked gauges. 

IIUC the capsules are the same with different embedded markings. That's my experience retrofitting gauges.

So your approach gets around the problem of finding the correct gauges or re marking them.

This topic made me buy some of that clear 3m tape that @PT20J recommended and put it over them, so that I won’t lose them!

I also keep tape and 2 1/2" cardboard squares with me that I tape over the dials when parked in the sun to prevent the black face from bleaching.

No luck searching, can you specify the tape?  Was the advantage of this tape that it adheres well?  Or does not hurt paint? Both?

I think @PT20J posted a specific link as well, but something like this: https://www.walmart.com/ip/3M-Clear-Repair-Tape-1-88-inches-x-20-yards-1-Roll/462161976?wmlspartner=wlpa&selectedSellerId=101281679

I went to Grainger to get it but probably any hardware store will have something comparable. Gorilla brand makes a similar tape. There is regular and "heavy duty". I'm unsure of the exact difference but probably thickness or tear strength, so I would think either is good for this application.

That's the stuff I used. It's supposed to be water and UV resistant. So far it has held up well.
