The Stovebolt Site Forums The Shop Area The Electrical Bay Water temp./oil press. vs. resistance curves?

The sensors on my 1938 Lincoln Zephyr three window coupe are the "King-Seeley" type. They use a set of points and a bi-metallic strip somewhat like the blinker cans on your turn signals. The gauges will work with the more modern variable resistance senders as I already replaced my fuel sender with a variable resistance type.
My problem is finding the resistance vs. temp./pressure curves so I can find the correct sender that matches up to my gauges. That data is not listed when you search the FAPS computer files. Does anyone know where this data might be found on the computer or other place? I plan to visit the NAPA store today in hopes they may have an old book still available.
This is a common problem for anyone who builds hot rods using a mixed bag of parts. Thanks

Hy beltfed, I'm no expert on anything F@#d, but our GM stuff usually uses the same resistance value for the fuel gauge, temperature gauge, and oil pressure gauges. So if you know the resistance for your fuel gauge that may work for the other sensors as well, hope that helps.

I am no expert but I was trying to learn about sending units and found this site which might help www.fordication.com/tech/fuel-sending-units-.htm

Update...the attempt to use a more modern variable resistance type sender ended in failure. I did find a book at NAPA that helped somewhat. The problem is that the sender I need is a negative coefficient type (as heat rises, the resistance goes down). The King-Seeley gauge provides to much current to the sender. It starts to heat up on it's own and goes into thermal overload. So I bite the bullet, get into "[censored]-national" and buy an original King-Seeley" type sender. Thanks for the help guys.
