As for "disregarding" the alert knowing that it is not an issue of uncovered fuel pumps, you understand that it is not a solution and cannot be tolerated.
@Piltdown Here's the note that we can read at the head of the LOW fuel C/L:

@skyjob I totally understand Boeing position and fully agree with it
The solution would be normally to put CMR at the highest alert level...or a software change on nonETOPS flights....
