66 Dart gas Gauge

Yours, must be good. What had happened on mine was my gas gauge would read sometimes and then it wouldn't. I noticed if I pulled the headlight switch in and out it would work, also tapping the dash above the switch sometimes that would work. The real kicker was when I replaced the switch the temp gauge started to work. I had replaced the temp sending unit a long time ago and it never worked. So that is the story..
