FUEL IN TANK
The auxiliary fuel pump is installed on the underside, left side of aircraft cockpit aft of the
fuel header tank. A two-position switch labeled AUX FUEL PUMP on the switch panel
electrically controls this pump. The pump is a positive displacement vane type with a
balanced-type relief valve, and provides a fuel pressure of 20± 1psi. This pump provides
positive fuel pressure for engine starting and may be used for continuous engine
operation in the event of engine-driven fuel pump failure. Maintenance and disassembly
of this pump is not authorized. Therefore, the servicing is limited to the removal and
replacement of the pump.
