Not sure that matters much. If the fuel can negoatiate the baffles
then I suspect the crud can as well. Hence the problem. Once the
fuel is shaken not stirred


Yes, but just bubbling up the fuel in one baffled area doesn't cut it.

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.

Capt. Bill

That may be true, and as long as it stays there the engine still
runs fine. If it does get shaken up, the a polishing system will
do its job while lessing the crud going through the engine filtering
system. Once initial polishing is done, I will be alternating between
tanks. One running while the other polishing. Getting things shaken
up is the best thing I can hope for.

Why not just always leave the polishing system in-line? Allow for a
bypass to change a filter or if it develops a vacuum leak, but other
then that, there's nothing wrong with always using "just polished" fuel.

That would require me to have 2 pretty much independent polishing
systems. I don't really have the room for that and the extra
expense would be hard to justify.

Pretty sure I posted a link early in this conversation that shows a diagram
of a polishing system based on a GCF F-1 filter that allows either polishing
or running with the F-1 as the first filter before going into the Racor
while running. If I didn't, or you can't find it, here it is again:

I guess I don't understand your system. Why would it require two
independent polishing systems? Even with a single set of filters (GCF
fillowed by Racor) you can use valves and piping to plumb the thing any
way you want.
