Installation of Temp Gauge

[tbirdtbird]

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
