gage display. However, due to the irregular shape of the fuel tank, the fuel quantity is NOT
proportional to the height of fuel in the tank, thereby giving a somewhat inaccurate reading of
fuel remaining in the tank. Later Scout models used a much more advanced Princeton sensor
to calibrate the fuel level at 5 points; Full,
¾
,
½
,
¼
, and Empty. This provides a much more
accurate measure of remaining fuel for the pilot. If you have the two point sensor, follow the
instructions below for calibrating the sending unit. If you have the Princeton unit, follow the
instructions in Appendix A of this manual.
Two Point Sensor Calibration:
The fuel sending unit must be calibrated using the procedure below to properly indicate the
range of operation. The gage is located under the rear seat on top of the fuel tank and just
below the electrical hot box. To access the adjustment screws, remove the rear seat by
releasing the velcro straps and slide the seat cushion forward on the seat belts sufficiently to
have clear access to the gage.
If the fuel gage must be removed for the EMPTY calibration, there are
two important
facts
to keep in mind:
