I don't think I would use one for an engine filter, but they seem to
be well suited to polishing.

My Yanmar distributor said that using any filter less than 30 micron
would void my warranty.

Mastry, my Yanmar distributor, does not like the paper towel filters AT
ALL.

I'n not convinced that these paper towel filter elements are a great
thing. When I pull a sheet off of a roll I can usually notice a fine
dust if I look close.

See http://www.trawlerworld.com/features_06.htm for a good polishing

system

based on the Gulf Coast F-1 filter and Walbro pump. I installed one like
this on my Krogen and love it.

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)?

Thanks!
