Sounds a lot like a ten-cent tail wagging a forty-dollar dog here.  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.
