Of course, understood. There would be more than just loadshed in that situation. It was just the DDG/MEL that was a little confusing.
BTW. I think the engines were providing thrust. Weakly, perhaps due to lack of fuel due to failed electrical pumps.
It's funny that Boeing/GE say that suction feed won't be an issue except during high altitude climbs. There may be 3000psi pump output, but I don't think there would be 3000psi of suck. The fuel has to go through a filter and two heat exhangers. I think I'd still be relying on some kind of check valve system to let air into the tanks.
Thanks and cheers
