B777 APU fuel imbalance

[applecrumble]

Hi guys,

we do some long turnarounds on the 777 where it is left on APU.
Is there a way to stop a fuel imbalance building? I can’t see a way but was just wondering?

Refuel it late on the turnaround - No imbalance for departure?

Load a bit more fuel in the tank that supplies the APU perhaps?
I don't know the B777 fuel system, but can you transfer centre tank fuel to the wing tanks?

The APU gets fuel from the left engine feed manifold. If you pressurise the centre tank pumps, or the right main tank pumps with a crossfeed open, you can use fuel from a different tank. Alternately, your ground engineer or refueller can transfer fuel using the defuel system to rebalance the main tanks later.
