Gas gauge is 1/2 to 3/4 inch below empty on gauge. I've put new sending unit, new CVR new circuit board. The car has a new wiring harness from Auto Wire. I'm almost out of ideas. Any help would be appreciated.

It stays the same, I only have .01 volts at the tank. Before I plug the CVR in I have 12 volts going in to t a when I plug it in it drops to 1.9 on the hot side and .01 coming out.
