Subject: Fuel transfer/polishing pump

Huh? Bubbling up fuel? It helps it as much as drawing the fuel from
one baffled area into the engine. Better to draw it into a polishing
system for a while.

But unless the fuel is shaken up real well most of the crud is still at the
bottom of each baffled area in a nice little mound.
