There was talk of an annunciation for the fuel pumps below 400kgs, then there was talk of an automatic shut-off, which apparently we have just had fitted, but I have not seen yet. The end result is flying with the extra fuel is going to carry on for the foreseeable future. Also there was talk of Boeing under taking a complete re-design of the pump to allow the AD to be rescinded. but with the 757 now out of production I would be surprised if that goes ahead.
