1. General
A. The left and right main fuel tanks can be gravity fueled through the over-. wing fill
adapters located approximately 10 feet inboard of each wing tip. Procedures for gravity
fueling the left and right main tanks are identical.
B. The center and forward auxiliary tank fueling is accomplished by using the right main
tank boost pumps to pump fuel through the defueling line and fuel fill valve, and into the
applicable tank fill line, (see Figure 303 ).
C. Fuel tank capacities and acceptable fuel specifications are shown on the fuel system
replenishment chart, General Servicing.

CHECK THAT MAIN GEAR INBOARD DOORS ARE CLOSED
BEFORE FUELING AIRPLANE.
A. Main Fuel Tanks
(1) Connect fueling unit/airplane grounding cable.
CAUTION: OBSERVE THE NO STEP AREAS ON WINGS.
(2) Use ladder or suitable stand at wing leading edge to gain access to overwing fill
adapter (see Figure 301 ).
(3) Connect fueling-nozzle-grounding plug to airplane grounding receptacle.
(4) Insert fueling nozzle in fill adapter. Slowly open fueling nozzle valve; commence
fueling.
(5) If main tank maximum fuel load is desired, fuel each main tank until fuel level
reaches overwing fill adapter screen retainer ring bead.
NOTE: Maximum usable capacity loads are 9841 lbs. for each main tank.
(6) If main tanks are to be fueled to less than maximum capacity, use following
procedure.
(a) Open fueling control panel access door..
(b) Place fueling control panel power switch in on position; verify that power
indicator blue light comes on (see Figure 302 ).
NOTE: If external electrical power is not available to supply the airplane load
buses, airplane battery power will automatically be supplied to the
ground refueling circuit when the fueling control panel power switch
is placed in the on position. Conservative use of airplane battery
power for fuel quantity indication is permissible.
(c) Momentarily hold fuel quantity repeater-indicator (gage) test switch in test
position to test indicators; pointers will move towards zero, when switch is
released, pointers will return to original quantity.
(d) Monitor main tank fuel quantity indicators (or magnetic dripless fuel
measuring sticks, if fuel quantity indicators are inoperative).
(e) Continue fueling until desired fuel load in each main tank is attained.
(f) Place panel power switch in off position.
(g) Close access door.
(7) Remove fueling nozzle.
(8) Disconnect fueling nozzle grounding plug.

CAUTION: MAKE CERTAIN FILL ADAPTER CAP IS LOCKED.
(9) Install overwing fill adapter cap; lock cap.
(10) Disconnect fueling unit/airplane grounding cable.
NOTE: Steps (11) and (12) should be performed on condition or at operators
discretion.
(11) Depress valve stem in fuel line shroud drain valve, located aft of right main gear
wheel well, to check for presence of fuel. Presence of fuel can indicate a ruptured
line (s) or loose connection (s).
(12) Drain forward auxiliary fuel tank cavity drain by depressing square valve stern in
valve located on lower right side of fuselage below auxiliary tank. Presence of fuel
at this drain indicates leak in auxiliary tank fuel cell and leak source must be
determined.
(13) Drain water from fuel tank sumps as follows.
NOTE: All fuel tank sump drain valves operate identically.
(a) Insert probe of drain tool in center recess of sump drain valve, and apply
upward force.
NOTE: Fuel should flow immediately after upward force is applied to tool.
The sump tool permits a fluid flow rate in excess of 3 gallons per
minute creating the siphoning action necessary to remove a maximum
amount of free water from the tank sumps and thus reduces corrosion
and soaping time.
(b) Drain tank sump until water ceases to flow.
NOTE: Fuel tank sumps should be drained after sufficient time
(approximately 45 minutes) for water to settle out of fuel. Sump
draining directly after landing may not be effective as water may be in
the form of ice and will not drain.
Depending on duration of airplane Turn Around time, tank sumping
may be more effective if accomplished immediately preceding
refueling operation.
(c) Check all sump drain valves for leakage; no leakage is permissible.

(2) Open fueling control panel access door, and defueling shutoff valve access door.
(3) Place defueling shutoff valve control lever to open position, (see Figure 302 ).
(4) Place fueling control panel power switch in on position; verity that power indicator
blue light comes on.
(5) Hold fuel quantity repeater indicator (gage) test switch momentarily in test position
to test indicators; pointers will move towards zero, when switch is released,
pointers will return to original quantity.
(6) Determine fuel load.
(7) Place center and forward auxiliary tank fuel fill valve control switch in auto fill
position; verify that tank fill valve manual control lever(s) moves to open position,
(see Figure 302 ).
(8) If applicable tank fuel fill valve(s) do not open, use following procedure.
(a) Place tank fuel fill valve control switch in closed position.
(b) Place manual fill switch in manual position.
(c) Place tank fuel fill valve manual control lever to open position.
CAUTION: OBSERVE THE NO STEP AREAS ON WINGS.
(9) Use ladder or suitable stand to gain access to main tank overwing fill adapter (see
Figure 301 ).
