(by the way the temp gauge from Herbs had the scale printed too high on the gauge face - something not obvious until the whole unit was put together

That is too bad. I don't understand why repo companies make such mistakes.

One of the most important diagnostics tools that Dana67Dart put me on to was using a gas tank sending unit to test proper function of the gauges

Thanks for the shout out but it was 67Dart273 who mentioned about the sender

So you need something that is either these three resistors or a variable (rheostat) such as a spare fuel tank sender, which you can set with your ohmeter
