Talking only about gas tank senders,
I have an old note from a guy that knew his stuff.
He passed away so we can't ask him.
60 ohms empty, 10 ohms full.
Gospel? Probably
not but ball park yes.
I would think the guys that repair sending units would know.

I know gas tank from 60-62 something like 10 ohms full 80-90 empty , the correct thermal style gauge temp senders must be same — as thermal gauges are identical in dash 60-62 , but gauges used in 57-58 ( and ? 59 ) are differential wound coils in the gauge , so no regulator needed , but senders for those might be higher ohms ,
