No!!! Don't go there! We don't need to prove that jet pumps
work, of course they do. Whether they are a good idea on an airplane is
another question. (I won't go there : )
Work on the PLANE, not pointless exercises !

Ernest,
Looks like I'll have to set up a test stand using a jet pump and
a
couple of 1 gallon cans and see if this idea has merit.

The
simplification is fewer moving parts and less pilot intervention.
The fuel just magically appears where it needs to be, and the tank
magically stay balanced.

Well, I expect to see you in church on
Sunday then 8*)
Actually, it's even worse for me. With only one tank,
I don't even have
a dog in this race. Just a topic that is a lot
more interesting than
BGP router test cases.
