Sender sends high temp

I didn't want to open the back cover on the new pump, and you wouldn't be able to see much in a photo without that open. But I did see through the outlet that both sides were cast correctly.

I installed the pump and heated up the truck. With the thermostat sensor reading 190, the gauge sits steadily at the 3/8 mark. This case is closed.

this is very late.. But what kind off water pump did you buy? I'm having the same exact problem as you.
