a) Immediately put the applicable fuel boost pump switch(es) to OFF if the LOW PRESSURE light comes on and stays on.
NOTE: When defueling or transferring fuel with minimum backpressure to the pumps, it is possible for the low pressure light(s) to be on. In this case, monitor the tank quantity and put the pump switch(es) to OFF if the tank quantity is not changing.
(2) Calculate the supply tank fuel to remain (Table 301):
TABLE 301
SUPPLY TANK TRANSFER (FUEL TO REMAIN) (LBS/KGS)
Initial Supply Tank Fuel Quantity INITIAL A:
- Transfer Fuel Quantity *[1] - TRANSFER B:
= Final Supply Tank Fuel Quantity *[2] = FINAL C:
*[1] Fuel quantity necessary for the tank with an inoperative gage (per the fuel sheet) *{2} Fuel quantity to remain in the supply tank after fuel transfer.

(a)
Make a decision about which fuel tank will supply transfer fuel.
(b)
Record the INITIAL supply tank fuel quantity, BLOCK A.
(c)
Use the fuel sheet to find the fuel necessary for the tank with an inoperative indicator.
NOTE: This is the fuel quantity that will be transferred from the supply tank.
(d)
Record the TRANSFER fuel quantity, BLOCK B.
(e)
Calculate the fuel quantity that will remain in the supply tank after the fuel transfer operation.
NOTE: Subtract the transfer fuel quantity (B) from the initial supply tank fuel quantity (A) to get the final supply tank fuel quantity (C). BLOCK C: is the fuel quantity that will remain in the supply tank after the fuel transfer is complete. When the supply tank fuel quantity decreases to this value, stop the fuel transfer operation.
(f)
Record the FINAL fuel quantity for the supply tank, BLOCK C.
(3) Transfer a known quantity of fuel into the tank with an inoperative indicator:
(a)
Transfer fuel from the supply tank into the tank with an inoperative indicator (AMM 28-23-0/201).
(b)
Monitor the fuel quantity decrease from the supply tank.
(c)
Stop the transfer at the final fuel quantity, BLOCK C.
(d)
Use the fuel measuring sticks to verify the actual fuel quantity in the tank with the inoperative indicator.
(e)
Record the fuel quantity on the fuel sheet.
C. Fuel Truck Flow Meter Method
(1) Transfer fuel from the tank with an inoperative indicator:
(a)
Make sure the fueling shutoff (refuel) valve(s) in the tank with an inoperative indicator are closed.
(b)
Make sure the receiving tank(s) have enough capacity to accept all of the fuel from the tank with an inoperative indicator.
(c)
Transfer all of the fuel from the tank with an inoperative indicator (AMM 28-23-0/201). 1) Continue the fuel transfer until the fuel pump low pressure lights come on.
a) Immediately put the applicable fuel boost pump switch(es) to OFF if the LOW PRESSURE light comes on and stays on.
NOTE: When defueling or transferring fuel with minimum backpressure to the pumps, it is possible for the low pressure light(s) to be on. In this case, monitor the tank quantity and put the pump switch(es) to OFF if the tank quantity is not changing.
(2) Calculate the upload fuel quantity for the tank with an inoperative indicator (Table 302):
TABLE 302 UPLOAD FUEL QUANTITY
Upload Fuel Quantity pounds (kilograms) *[1] LBS (KGS) A:
/ Current Station Density / DENSITY B:
= Target Quantity, gallons (liters) = GALLONS (LITERS) C:
*[1] Fuel quantity necessary for the tank with an inoperative indicator (per the fuel sheet).

(a)
Record the fuel sheet upload fuel quantity in pounds (kilograms), BLOCK A.
(b)
Record the current station DENSITY, BLOCK B.
(c)
Convert the fuel sheet upload fuel quantity in pounds (kilograms) into gallons (liters) by dividing pounds (kilograms) by the current station density.
(d)
Record the target upload fuel quantity in GALLONS (LITERS), BLOCK C.
(3) Upload a known quantity of fuel into the tank with an inoperative indicator:
(a)
Do a pressure refuel operation (AMM 12-11-02/301).
(b)
Monitor the fuel flow meter.
(c)
Stop the upload at the BLOCK C fuel quantity.
(d)
Put the fueling shutoff (refuel) valve switch in the CLOSED position.
