2 wing tanks (left and right), 2 fuselage tanks (left main-afterward and right main-forward)
2 wing tanks (left and right), 2 fuselage tanks: main-aft linked to left system and main-forward, linked to right system, up to 3 external tanks (2 wings and 1 fuselage).
Up to 3 external tanks (2 wings and 1 fuselage).
Normally the left wing and left main tanks feeds the left engine and the APU,
the right wing and right main tanks feeds the right engine. The two feed lines could
be interconnected by opening the cross feed valve.
The wing boost pumps will supply the respective engine until the wing tanks are empty,
at which time the wing boost pumps will automatically shut off. The main boost pumps will
then supply the respective engine with the remainder of the fuel in the airplane.


In case of a wing tank boost pump failure, the wing tank fuel will gravity feed to its respective

Unequal fuel level between right main and left main tank (imbalance superior 750 lbs) will cause a longitudinal CG shift that may exceed allowable limits. In this case, a valve named "tank gate" could link the two main tanks.
 
Fuel from the external tanks is transfered to the wing or main tanks by pressure from the bleed air system. Wing tanks can be topped when the fuel level is below 1590 lbs.
Main tanks can be topped when the fuel level is below 3034 lbs.
Main tanks can be topped when the fuel level is below 3034 lbs.
