Fuel Level Sensor Tables
The table below gives approximate internal resistance and raw voltage values for a Fuel Level Sensor based on fuel volume. These can be used as a general reference when the actual values are not available for any single tank or saddle tank Fuel Level Sensors.
As can be seen in the table, the full travel of the sensor (Full Stop/Empty Stop) is slightly more than the full tank and empty tank thresholds used for the fuel gauge.
