Gas Gauge

The metal clips snapped onto the fuel lines is the ground strap. Now that we know all 3 stock gauges are dead we know the limiter in the fuel gauge is dead.
The voltage limiter that is normally found pluged into the back of most panels in inside the fuel gauge on rallye panels.
I'm guessing what you thought was the voltage regulator is actually the noise supression capasiter. Go here and read ... www.DeMonIVR.com
I get it, I had no idea the voltage regulator was inside the fuel gauge, that explains why one of the gauges I have is burned out on the back.
To clarify, the metal clips are snapped on to the fuel lines, but that is it, there is no strap between them.
So, I need to get me a ground strap, a DeMonIVR, and go from there.
Looks like a nice piece, thanks again.
