Good point. I am painfully aware of how fast a Raycor clogs up
with dirty fuel

You need to look at depth filtration for polishing vs. surface filtration
like the Racors. They will clog up very fast if you have dirty fuel. See
the
link I posted earlier, and take a look at depth filters like the GCF F-1
or
Jr.

I don't have a filter problem, I have a pump question.

I am designing a fuel polishing and transfer system. My thought
is to use valves to route fuel from any tank to any tank. No
problem with that part. I want to be able to just transfer fuel
or switch in a filter to polish the fuel while transferring. Since
I can select the same tank for source and destination, I can
polish fuel in place as well. The problem comes with the selection
of a pump. I was looking at a Groco or Jabsco pump which seems
good for transfer purposes, but way exceeds the flowrate of the
filter when polishing. A Walbro fuel pump (which I have as a priming
pump now) seems like a good fit for polishing (33 GPH) but will be
slow
when just transferring fuel. What happens when a 5.5 GPM pump
(Jabsco) is pushing fuel through a filter rated at 60 GPH (RACOR
500)?

Have built the system above which BTW, uses a lot of 1/2" bronze ball
valves.

You solve the filter problem in a straight forward fashion.

Multiple filters (Larger than 500) in parallel to reach at least 60
GPH.

I'd built in a safety margin and shoot for at least 75 GPH.
