You take a post of mine that was adressed to rabend as seen in the quote and take it up as if it was adressed to you. Your situation is different as you took a filter for a 600 hp engine
in some kind of brute force attempt at beating manufacturer recommendations.
Anyway, 2 microns for prefilter is madness. You can find the recommendations in this document: http://www.racor-filters.com/images/...bineSeries.pdf
at page B63.
It says 30 microns is primary, 10 microns is secondary and 2 microns is final.
You must have missed it.
No I did not. Sorry I replied with a different idea to your masterful comment to another response.
The 1000 series is fine for my application and has a much better separation with a 2 micron filter up front Then a 10 /20 500 system. I have a single
1000 2 micron. My cummins has its own separator and filter right at the pump. Water
is most likely the big hazard to an engine. fuel gunk is either bad maitenance or water
. Either way my 2 micron filter with a large surface area and separator is easy to change and no doubt catch all the crap or water. Think having large capacity very fine hydrophobic surface filters is a good plan. Idea is very fine filtration 2 micron on hydrophobic membrane in a turbine. Got a few years on this setup and a few miles past. You really need not stuff all that polishing gear
in line. Very efficient high surface filtration and good fuel treatment should be the first point. Ciao buona notte nick
