67 Cuda instrument voltage regulator

Thanks for the input....seems that upon closer inspection, the fuel guage is bad along with the voltage limiter inside it. The small, hair-like wire running from the needle side of the guage to the regulator side is fried also. Not sure how, or if this can be fixed. This is the 3rd used fuel guage that I have purchased that is bad.
Open to any ideas or suggestions..need to get the dash buttoned up soon..Larry
