@ATAG_Ezzie did you read cockip instruments and systems description ingame?

 

Fuel System Control Panel
The panel includes the following:
...
Two external tank fuel level indicator lights (External tanks empty indicators). The corresponding light illuminates when the fuel in the external tank is completely depleted. When the pressurization switch for the corresponding tank is set, the light extinguishes.
Two three-position external fuel tank pressurization switches (External tanks air pressure switches). These are used to activate the pressurization of the tanks on the pylons under the wing or on the wingtips when set to the corresponding positions (the PYLON TANKS AIR PRESS or TIP TANKS AIR PRESS position) or to deactivate the pressurization of the external tanks.

Fuel System Selector valve
The fuel supply mode selector valve directs fuel from the selected tanks to the fuel pump. The selector has four positions: OFF, ALL TANKS, WING AUX, and FWD AUX. In the ALL TANKS position (normal operating mode), all feed pumps are activated and transfer fuel to the main fuel tank. Fuel is supplied to the engine from the main fuel tank. The WING AUX and FWD AUX selector positions are used if the main tank or its fuel line is faulty. In the WING AUX position, the feed pumps supply fuel from the wing tanks directly to the engine-driven fuel pump, bypassing the main tank. The other feed pumps will not operate when the valve is in this position. Similarly, the FWD AUX position controls only the front tank feed pump and directs fuel from it directly to the engine-driven pump. Since the WING AUX and FWD AUX use direct supply lines to the engine-driven fuel pump, these positions are effective even in the event of a failure of the wing or forward tank booster pumps, since the suction force of the fuel pump is sufficient to maintain full engine RPM at altitudes below 6,000 feet.

 

 

The aircraft’s fuel system includes: two fuel tanks installed in the fuselage, each equipped with a booster pump; five interconnected fuel tanks with booster pumps; and provisions for attaching external tanks to the wingtips and on underwing pylons.

During normal system operation, fuel from all tanks is supplied to the main tank located behind the cockpit in the upper part of the fuselage. From the main tank, fuel is then supplied to the engine through an engine-driven pump. If necessary, fuel from the wing tanks or the forward fuselage tank can be supplied directly to the fuel pump. To do this, the fuel selector  valve must be set to the appropriate position.

Thanks Garrick - I missed seeing this in the in-game notes so thanks for highlighting. 
 

Good to know re the bypass capability if there’s damage. 
 

Thanks

Ezzie
