Does anyone know if both engines feed off the same tank(s) on
approach? It was at the end of a 10 hour flight wasn't it?


Don't know about the 777 but I've heard that on the A320 and A330,
there are six main pumps - two in the center tank and two in each
inner tank, and each engine is fed with one pump in the center tank
and with the two pumps in its own side inner tank. When inner tanks
reach low level, valves between outer and inner open and an automatic
gravity transfer occurs (on one of the A330 variants, fuel transfers
from center tank to wing tanks are managed through a transfer valve).

Nope. You can't transfer fuel from one tank to another in flight.
