I have a 98 trans am and the fuel gauge reads backwards. I was told by the previous owner that when he switched fuel pumps, he used a sending unit out of a 99. Works fine, just backwards.

Everything I have read about backwards gauges people have used a newer computer causing this. And the fix was in the tune. But nothing about a newer sending unit.

Is there an easy fix for this?
Thanks.

Switch the two purple wires.

the purple wires back at the pump?

Yes. The plug in the fuel pump module

Switching the wires does nothing. It is not polarity sensitive.

If he installed a 99 sensor, it rotates the opposite way of a 98, so it should read backwards.

No idea if there is anything similar in the US.

But this will allow you to change any resistance scaling...to any that you need
