This is where it got confusing for me a few years ago because there are 2 filters on the W27 engine itself and both are Westerbeke parts. Your Racor(s) would be the 3rd and 4th filter(s).

Wow–did not know about those.
Here is a picture. Both filters were full when this was taken–and then later on the front one went to half full.

A similar setup to mine. Page 54.1 shows 3 filters in my manual. If you follow the line from the Fuel Shutoff Valve, you will first see the “Water Separating Fuel Filter”’ (that’s your Racor). Next on that line is “Primary Fuel Filter” and then “Secondary Fuel Filter”. These are much smaller and attached to the engine. The Seconday FF is part of the fuel pump.
I would recommend you remove one Racor altogether, (if it hasn’t been disconnected already.) I see no advantage to 2 Racors as long as you change the other 3 filter elements regularly. In fact, if the second Racor is connected it may be a disadvantage inasmuch as the fuel pump is working harder and there is more potential for fuel starvation and/or air leaks.
Joe Valinotti is the Guru. Don’t know of he’d agree…

Thanks for the complement, warranted or not. What I’m looking at in that diagram, is the 1st or “Water Separating Fuel Filter” would be the Racor. The 2nd one listed as the “Primary Fuel Filter” is the one on the engine and the 3rd or last one is really the strainer in the fuel pump itself. It seems to be a matter of semantics or a nomenclature problem.

Since I was going to change my single Racor filter tomorrow with a 20 micron filter, does any one know if the 10, 20 or 30 is ideal and why?

My Racor--on a W27 on a Nonsuch 30-- has a 2 micron (not 20) filter because that's the way the previous owner's diesel mechanic set it up. The theory is that then this is the only filter you need and the only one that needs to get changed. The boat has been set up this way for over 12 years without apparent ill effect. The previous owner's previous boat (a Nonsuch 26) was set up the same way. I suppose you may need to change the filter more frequently, but it is an easy task.

Actually, I use a 2 micron and never have to change the one on the engine.
