Re: Fuel Filtration Systems

I found my links to articles on fuel/oil polishing. Worth the read.

I think you are misunderstanding the function of this valve. It cannot let fuel pass when the element is blocked.

This diagram makes it a bit clearer:

If you have one of these filters make sure you take a look at Maine Sail's excellent rebuild instructions:

Nice engine room BTW .

Yup, like Noelex already said above, the "turbo action" (or "turbine action" I believe Racor calls it) is nothing to be excited about. In my honest opinion, it is nothing more than a marketing gimmick to justify a higher price on these "superdupersecretweapons" of fuel filtration.

The single most important factor is FILTER ELEMENT SIZE. Period. You are best served by getting the biggest unit you can fit in to your engine room and still change the filter easily. If I recall correct this was discussed in another thread. But anyways, nobody should think these "turbine actions" do wonders in your regular pleasure boat. Maximize your filter element size by getting the largest unit you can fit and service insitu if you have concerns.
