I pulled the old gauge and replace it with a new one.
I am having an issue with what seems to be a grounding issues.
If I using an ohm meter both side of the fuel gauge and the temp gauge read
a direct ground to the gauge frame itself. When I hook up the power wires, one to the power side and the other from the gas sender unit, I can read 12 VDC from the frame of the gauge cluster to ground.
This is strange, as the old one reads the same.
I looked and insulators etc, all good and the new one looks the same.
Ideas???
I can send pics too
