Had the same problem with mine, bought a new sending unit and pulled the old one to find the float had a hole in it. Floats can be replaced so before you buy a new gauge check the float.

Does the temp gauge work as it should! This will tell you the voltage limiter in the dash is fine.

Yep if you didn’t install in the car check it out first. Do an ohm check on the sending unit. Heard many stories that the new sending units don’t work right.
