[Man With A Gun]

So a non functioning system with the fuel meter pegged at 3:00 ( way past full) would indicate an open circuit?

I've got the dual tanks in my '86. Left tank reads just fine. Right tank reads past full although the tank works otherwise.

Where is the likely problem? Need to replace the fuel level float sensor? Broken wire somewhere? Bad ground? Bad fuel selector switch? Bad connection?

Where specifically and what specifically should I look for?
