ENGINE AND APU FUEL FEED PRESENTATION
PUMPS
Each main tank has 2 centrifugal booster pumps capable
of supplying the engines with fuel at the required
pressure and flow rate.
There are 2 pumps per tank.
The wing tank pumps run continuously during normal
operation.
SEQUENCE VALVES
Pressure relief sequence valves on the wing tank pumps
give priority to center tank pump supply.
The sequence valves give priority by limiting wing
tank pumps output pressure.
CROSSFEED VALVE
A CROSSFEED VALVE permits connection of the left and
right engine supply lines.
The crossfeed valve is normally closed.
LP VALVES
The Low Pressure valves isolate the engines or APU
from the fuel supply.
The LP valve is open when the related engine or APU
is running; it closes when engine or APU is shut down
or when FIRE pushbutton is released out.
PRESSURE SWITCHES
A pressure switch for each pump monitors the pump
pressure for the low pressure warning.
APU PUMP
A specific fuel pump supplies the APU if the tank pumps
are not operating. This pump takes fuel from the left
