Makes sense, but there is quite alot of evidence out there that
a polishing system is a good thing to have. I can't really
increase the size of my on-engine filter. I could increase the
size of the Raycor, but at the pore sizes I run (30 micron) in it make it
necessary to change the on-engine filter regularly as well.
Bigger Raycor won't fix the problem.

Unfortunately that fuel clogs up the filters. That is the entire problem.
Having clean fuel in the engine fuel system avoids the problem.


Just go up a size or two in your filters. The surface area difference
between a
500 Racor and a 900 Racor is tremendous.
Many times on a boat with filter clogging problems, I have just installed
a
larger filter system and the time between changes has gone back to normal
with
no more clogging in heavy seas problems.
