Another point, those 2 micron filters on your Racor, check with your
engine manufacturer, I've never heard of one reccomending more than a
30 micron filter as the promary. Using more restrictive filters can
cause problems with your supply pump, or, even worse, cause the engine
to run lean. That will cause the engine to run hot and, over the long
run, cause all kinds of other problems.- Hide quoted text -



As I recall, if you check with Racor I think you'll find the 2, 10 and
30 micron filters have the same flow rating. And for the most part we
are talking low power, low flow rate engines here. So it's really a
non-issue.

FWIW I've been running 2 micron Racors on Lehman 120s and 135s, as
well as other brands, for decades with no problems of any kind.
