I've seen minor differences from one gauge temp sender to another, like
having several good used ones to play with .....like a needle's width
difference between one sender and another.

you can try adding a resistor  - wild guess 1K ohm.   I have used 2.2K ohm
resistors on Subaru gauge senders to VW gauge I think.  The 1K ohm is purely
a wild guess.

I always think about the voltage stabilizer on the back of the instrument
cluster in any case like this.

I almost think I have more faith in good used original ones than new ones.
