    If tank is all the way full, run it for a few gallons, then see how much fuel it takes to fill it back up; then repeat for twice as many (or so) gallons.

    I had to switch F0501 it back to backwards and it worked. I also changed F0507 to look a little more like the 98 PCM and it seems to be fairly accurate. Log showed 60% fuel, gauge showed almost 3/4, added about 7 gallons of gas and it read full. So I'm confident that the first half of the gauge works. I'll run it empty and verify that everything looks good at some point.
