Right. I've got an FGE. I know the sump for the retract is a little
different. Perhaps they would be able to recover a little more fuel.
The ram air idea has me interested. I could do the math, but someone
here probably knows: How much PSI is required to raise a fuel column
one foot? Would ram air from the outboard end of the strake be sufficient
to evacuate the sump tank while in flight?

I have seen one, but have not disassembled it. I suppose I
could ask Dennis Miller if he minds. It's sitting in my warehouse
attached to a brand new 6A350.
