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.

Didn't we set out to *simplify* something?  How about just ONE line 
from B to A with a Facet pump.  To get fancy, you could have a 
momentary ON for the pump that would cause it to pump for 2 or 3 min 
or something and then turn itself off. 

Just trying to stay on message ... Jim S.

    

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.

  
PS  Has anyone actually *seen* the two-line-jet-pump and watched it 
actually WORK ??
(the devil made me say that )
    


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.
