I now see there are other posts regarding this topic.

One question... Is the APCO gauge mechanical or electronic?

Thanks

May I piggy back on your question and ask about a temp. gauge with a tube from the sensor to the gauge? How can I repair it if need be, it apparently doesn't indicate. I'm going to pull the sensor and submerge it in hot water. If it works I'm fine, but if there is no rise in the gauge, what next? Thanks
 
That is not a wire, it is a tube that senses pressure with heat. Once you cut it, you now have a wall ornament.
 
That's what I thought! Just like my MGA gauge
need a pretty big hole to run the cable through the fire wall... ick.

Running thru the floor boards many holes would save firewall extra hole

That might work... seen a couple posts one going alone side of steering box.

Also saw a pic where someone stuck through at the terminal block but no detail on how ?

Closer to the speedo the better.

thanks for the info
 
why use that gauge?
The dial has a very small sweep, thus is not very accurate.
The probe is mechanical, in this case filled with ether which expands with heat. Can be troublesome
Why not use an electrical sender, that way you are only running a wire
Your FLAPS will have a bunch of temp gauges to choose from. Getting a black and white face is no problem, or whatever you choose. The sender and gauge come in one box. Large sweep= much greater accuracy. Marc H. can better explain why this is than I
 
I did the hot water test of the sender unit in my top his connection, gauge worked fine, This being a car new to me I hadn't tested it before and had never seen it move much if at all. The hot water had it shoot right up the scale and it coincided reading with a thermometer I had placed in the water. I'm good to go for a while at least. Thanks for the tips on a replacement gauge when the time comes.

What are the FLAPS that you are referring to ?
 
installed Apco gauge with under instrument panel black single mount.
Fit great and looks even better.

Was able to route through terminal box with small cutout in cover. I am not putting the light in. The OEM dash light illuminates the gauge nicely.

On to next project!

When shopping for Mechanical Temp Gages or Moto-Meters @ swap meets, take along a BIC lighter to test them with. When buying new repro temp gauges, test them in boiling water, to see if they're reading 212 degrees. Chuck went through 4 new NAPA gauges, to get one that was ACCURATE! (Made in CHINA!)
