What would cause a fuel gauge to peg way past full?

Re: What would cause a fuel gauge to peg way past full? Generally, if your gauge is reading past full and the tank isn’t full, it’s the positive wire that has a connection problem.

What should fuel gauge read if tank is full?

Take an ohmmeter and see what the resitance is between ground wire and the purple wire. If the tank is empty, it should read around 0, if it’s full, about 90 ohms. If that’s right, then check the wiring going to the gauge for excessive resistance.
