My temp gauge reads about one increment high. When the water temp (measured by temp gun) is at 160 (should be the center mark) it reads 180 (the mark half way from center to the Hot mark).

The gauge seems okay. It buries on the hot side when open circuit, and buries to the cold side if the sender wire is briefly shorted to ground.

The right side (single connection) sender is a reproduction. I can not find a NOS or used original unit.

Is there a source for OEM senders?
Is it worth $45 to try a new repro sender? If so, are they all the same, or is there a better quality supplier?
