You always want to stop contamination at the Racor's. One they are easy to change and you can also see what the problem is if any. In a perfect world the engine filter will never see any contamination. Forget 30 micron filters, the only thing that will do is keep an alligator out of the fuel system. If you live in an area where you get good diesel fuel, I would try the 2 micron filters in the racor filters. If you find that you have to change then to often then go to the 10 micron filters. Always drain the racor sump drain daily. It is cheaper to change a filter than an injector or injector pump. And always keep at least two extra set of filters with you in case you run in to a bad tank of fuel.

After the Racor you would have either a cartridge or spin-on for your secondary filter. A thirty micron filter(orange on both ends) would let far too much through which then plug up the spin on. Racor filter number one should be a 10 Micron filter (blue on both ends) minimum. The spin on or final filter before the injectors should be 3 micron or equiv. Tan or beige on both ends which is I believe 3 Microns. Which boat do you have??? Are your engines 555 Cumins?? orDetroits??
