Thanks Mike
Yes, it's marked 90 ohms, I've got an ohmeter, and I know how to use it! It was working when I parked the car a few yrs ago.
If it's an original sender, I don't trust the 50 yr-old mechanical feed-through connection after reading some other threads but I can deal with that...
If I decide to replace it, Tanks Inc. sells a
sending unit they describe as "stainless steel construction". This sounds appealing. Anyone have any issues with this brand?
Mike
