Does anyone a schematic for a 67 442 with rally pack . Were trying to figure out our gas gauge problems. I have replaced everything but the gas gauge and it still don't work ( stays buried past full ). We have good grounds as we thought that was the problems. I wondering if the gauge is bad. If so does anyone have a extra one or anyone have any ideas ?

 

The gauge has a constant 12v on one side and the lead from the tank on the other. Remove and ground the lead from the gas gauge at the tank and see if it goes to "E". You can also do this at the gauge to test the gauge.
