10-60. GENERAL
The PA-28-151, Wa r r i o r, and PA-28-161, Warrior II, have two fuel quantity gauges mounted in the
cluster on the instrument panel. These instruments are calibrated in fractional divisions of one fourth, one half,
three fourths and full.
The PA-28-161, Warrior III, has two fuel quantity gauges, mounted in a common circular instrument,
located on the pilot's instrument panel just the right of the control wheel. (Refer to Figure 10-9.)
In all three models, a transmitter unit is installed in each fuel cell. This unit contains a resistance
strip and a movable control arm. The position of this arm is controlled by a float in the fuel cell and this posi-
tion is transmitted electrically to the indicator gauge to show the amount of fuel in the cell.
Refer to Section IX, Fuel System, for procedures and information required to check and calibrate both
the 14 Vdc and 28 Vdc fuel gauge and transmitter.
