Rob, I'm a little ways from starting the engine, so the fuel tanks are empty. But the fuel tank display on the 4500 EFIS indicates the tanks to be full. I want to fix this so it indicates exactly what fuel is in the tanks (none). I've looked in the installation/user manual, but can't see where it addresses calibrating the 4500 and when I follow the steps outlined I get no where. Tell me I'm overlooking something simple and what that something is.

Thanks,

Terry
