Oh Boy....what a shambles of differing responses to that fuel management question...
The appropriate procedure for your model of 737NG will be provided in your personal copy of the FCOM Volume 1, Normal procedures.
Whatever is provided there is what you will do..
I've never heard such a confusing shambles of half-truths and second-hand rumours..
This is a very important aspect of your everyday operations, I'm completely gobsmacked each and every NG pilot doesn't know these backwards!!
'nuff said from me...
