Find the resistor behind the panel for each of the gauges and short it. You will then have fully functioning gauges that displays correct values instead of averaged. Ford got a lot of complaints around then because the gauges were reporting out of tolerance conditions.
You are on your own for the fuel tanks, my 38 gallon single has weird characteristics: 160 miles before it comes off the full bump then drops like a rock to 3/4, then reacts irrationally to 1/2. Below 1/2, it is a reasonable relationship to fuel/mileage. Thank god for the odometer.
