The OEM AMM officially refers to it as the Engine Fuel Suction Feed.

I stand corrected: thanks. The point I was trying to make was that, in the event of failure of all the tank pumps we are not actually relying – as you know better than I do – on the ability of the HP Pump to suck fuel from the wing tanks to the engine: gravity will do the job. On all the aircraft I flew with pylon-mounted engines, this mode of operation was known as gravity feed, not suction feed. I wonder why the B777 uses a different term.
Thanks also for the references to the posts in which you established beyond reasonable doubt that the wing tanks had plenty of fuel remaining: I remember the discussion only too well. It's worth mentioning that, if the remaining fuel had all been in the centre tank and the centre tank pumps had failed, the only possible way of getting fuel to the engines would be by suction. This was, however, plainly not the case.
pacplyer,
Suggest you read my post again more carefully?
