Post 747-400 HST Refuelling
I've noticed that many airlines have rid themselves of the Horizontal Stab position warning light on the wing fuelling panel and that a stab position outside of 5~7 units no longer prevents fuelling of the HST. Was their some kind of _mechanical_ modification made to the HST or its associated plumbing which now allows refuelling in any position?

NB: I believe Boeing(?) Service Bulletin #28-2155 refers to the modifications carried out, but I don't have ready access to them.

Thanks.
Rdgs.
