I'm going to venture a guess here. The specific gravity of E85 is different from regular unleaded. The float would be at a different spot physically per the volume of fuel in the tank. I bet it is simply a resistor that when the other valve (mystery valve I mentioned) detects E85 it either throws it in series with the sensor or connects the sensor directly to the gauge depending on if the sensors resistance is higher at the top or lower at the top (full). The higher the specific gravity (water is 1.0) the higher the float will sit in the fuel. Regular unleaded is between .72/.77. E85 is almost exactly .79. Intriguing!
