Why fuel pump in tank 1 switched on after apu start?
@SelvanSelvaraj

Normally APU takes fuel from Left wing tank through Gravity Feed. There is no separate fuel pump for APU as in A320 aircraft. Gravity feed is through the fuel feed line (for engine#1) on LH Wing. So Fuel Pump of LH tank is normally kept ON to supply a Positive Fuel pressure though it is not really required.

Moreover the fuel boost pumps require AC power to operate which will be available after APU start..

@@SelvanSelvaraj Gravity fuel feed requires the fuel to gravitate😉 Meaning the fuel tank must be above the apu.. If you dont use AC boost pumps to supply fuel (I dont) the APU DC boost pump will (automatically) supply fuel from the left main tank. If the AC and DC boost pumps do not supply fuel, the APU will suction feed from the left main tank.
