Obviously, accurate readings are dependent on both the sender and the gauge being in "sync" with each other. If the gauge is off, the correct sender resistance will give a bad reading, and vis versa.
There is a lot of good info here:

Buck Trippel has mentioned in the past a neat adjustment he has sometimes made. It seems the senders these days are often low on the resistance scale compared to what they should be. If the sender resistance is a bit low across the board, just add an additional resistor is series at the gauge input terminal. Or do it based on the temp you want to have the most accurate reading. And heat shrink insulation around the resistor and its leads for safety.

You are welcome. Sometimes I am more successful than others.
