Hawker 800 XP, Pilot Training Manual

Page: 187 / 504

INTRODUCTION
The Hawker 800 XP fuel system includes left and right integral wing tanks, and an auxiliary
ventral tank located in the rear fuselage.
This chapter covers the operation of the fuel system up to the engine-driven fuel pump. At that
point, fuel system operation becomes a function of the engine. Refer to Chapter 7, “Powerplant,”
for additional information.
GENERAL
One electric boost pump in each wing tank de-
livers fuel under pressure to its respective en-
gine during normal operating conditions. Each
boost pump operates two jet pumps. The jet
pumps transfer fuel from the outer portion of
the wing tanks and the ventral tank to the fuel
sump compartment where the boost pump is
located. This also ensures an adequate fuel
reservoir for the boost pump. Fuel may be
transferred from the ventral tank into both
wing tanks. The fuel system has both gravity-
and pressure-refueling/defueling capabilities.
All tanks can be pressure-refueled or defu-
eled simultaneously.
