Racor 2 Micron vrs 10 Micron
Look, everyone gets to live with their own decisions.
If installing 2-micron primaries is a way to defer
routine maintenance on the secondary filters, its
asking for trouble. Until I see some real evidence
(rather than supposition) that suggests there's a
whole bunch of junk bypassing a properly maintained
10-micron primary and clogging a properly maintained
2-micron secondary, I'm going to follow the
recommendations of engine and filter manufacturers -
especially since it's their warranty money and R&D
money on the line. I just don't think they'd be making
these recommendations if it wasn't sound advice - they
would stand to lose a lot and gain very little.
Just my opinion -

Hello Peter
There have been a lot of posts on this and you may be mixing up mine with
some others. I'm not suggesting that the traditional primary secondary doesn't
work or that the primary will allow large amounts of dirt to pass thru and
clog the secondary. If the traditional system is right both filters will collect
dirt as designed definitely no "Oh My Gawd" My position is that the only
advantage to the traditional system is more filter area because both filters are
working at the micron level installed. The same thing can be accomplished by
increasing filter area on a 2 micron primary.
Unlike the "experts" in your link I believe the vacuum gauge is extremely
useful over the entire RPM range if you use it correctly. With new elements in
place I take readings at various RPM to get a baseline to work from I'm more
interested in change then the actual number. I also never suggested that the
final can be left in forever it won't need to be changed as often as the
primary but should be changed periodically so as not to deteriorate from age or
moisture.
The big difference in my way of thinking and yours or your "experts" can be
best understood 150 miles offshore on a snotty night. I can glance at a vacuum
gauge and know the overall condition of my fuel system and you can't.

Regardless of which camp you are in, no one has really suggested using the
wrong size filter will cause any damage as long as the filters are changed
when required. I have 2 micron in now and will see how long they last
before needing replaced - I also decided to spare both sizes just so I have
a choice when I do replace them next time...
