I have a Universal M18 diesel with about 600 hours. Seems I only have 1 fuel filter, the one on the engine, I want to add a racor water seperator. Not sure what model to get, 2 micron, 10 can't seem to get a staight answer.also should it be installed before the lift pump?Thanks

This might help
Rick Checl out this Yanamr link which has some generic info. The conventional wisdom is either a 30 or 10 micron primary and a 2 micron secondary filter. Don Illusion

Primary filters....
Rick, I'd recomend a Racor 120 series with a 30mcn filter. West Marine part#309918. Install the filter between the tank and lift pump. Also read this service buliten from 2003. SERVICE BULLETIN #238 DATE: 28 FEBRUARY 2003 MODEL: ALL MODELS-DIESEL PROPULSION ANDGENERATORS AND GASOLINE GENERATORS SUBJECT: FUEL PUMP INLET FIL TER PN#048076 A FILTER IS BEING ATTACHED TO THE INLET OF "ALL" FUEL PUMPS ON BOTH DIESEL PROPULSION AND GENERATORS AND GASOLINE GENERATOR MODELS BEGINNING THE LATTER PART OF MARCH 2003. (MANUFACTURING DATE CODE E303) THIS IS BEING DONE TO ENSURE THAT THE FUEL ENTERING THE FUEL PUMP IS BEING PROPERLY FILTERED TO PROTECT THE FUEL PUMP FROM CONTAMINATION. THE INLET OPENING OF THE FILTER IS THE SAME AS THE INLET OPENING IN THE FUEL PUMP (1/8 X 27 NPTF). THIS SHOULD POSE NO PROBLEMS WITH EXISTING FUEL LINE CONNECTIONS. THIS FILTER "MUST" BE USED. IF THE FILTER IS REMOVED WARRANTY ON THE FUEL PUMP IS VOID. THE FILTER SHOULD BE REPLACED ON A NEWLY COMMISSIONED UNIT AFTER THE FIRST 50 HOURS OF OPERATION. THEN EVERY 250 HOUR, ANUALLY OR AS NEEDED. WESTERBEKE CORPORATION STILL RECOMMENDS THE INSTALLATION OF A PRIMARY FILTER/WATER SEPARATOR BETWEEN THE FUEL TANK AND THE ENGINE. THE FILTER USED IN THIS SHOULD NOT HAVE A MICRON RATING SMALLER THAN 10 MICRONS. Pat McCartin Inland Marine Diesel Buford, Ga imd_ga@hotmail.com

Racor First
The order should be fuel tank Racor electric pump (separate from engine if you have one) engine mounted filter injectors The reason is that the separate electric fuel pump has a small filter in the bottom. The Racor filters out gunk first to avoid messing up the small screen filter on the electric fuel pump. Stu RACOR FUEL FILTER NUMBERS From the Racor 220/225R Spin-on Series Manual: R24S 220R, 2 micron replacement element R24T 220R, 10 micron replacement element R24P 220R, 30 mciron R26S 225R, 2 micron R26T 225R, 10 micron R26P 225R, 30 micron S - 2 micron; T - 10 micron; P - 30 micron As I recall from being in the store on Monday, the 15 series is a much thinner (shorter) filter. The manual covers two different separators, the 220R and 225R. 220R is for 30 gph, the 225R is for 45 gph, I'd bet we have the 220Rs.

There are two views on that electric pump...
...and where it should be placed. One view is represented by Stu's description, for the reason he gives. The other view is that the electric pump should be placed in front of the Rador, immediately downstream of the fuel line from the tank and its shut-off valve. The logic for this placement is that it makes the entire fuel system easy to prime, and it especially makes the filling of the Racor, after a filter replacement, quick & convenient. The basket filter in an electric fuel pump makes no contribution to the cleanliness of the fuel your engine will see, given the Racor and engine-mounted fuel filters. This basket filter is there because some fuel systems offer fewer filtering options than our typical boat installations. When placed in front of the Racor, just remove the basket. The less you use your boat and/or the less you do your own engine work, the less important it might seem to have an electric fuel pump. For those of us who do our own work and use boats more regularly, an electric pump (usually installed by the owner, not the builder) is highly convenient and, given its cost, excellent value. It's other advantage is that, should your onboard fuel pump fail, you can flip on your electric pump and keep the engine running. This used to be a minor point given the old-style diaphram lift pumps found on marine diesels. These days, the pumps are designed differently and, according to the mechanics I talk to, their failure rates are much higher. Jack

A few points to counter your arguement. The Universals all use an electric pump mounted to the engine. Second all Racor filter except the 120 series contain a check valve that prefers to opend from vacuume not pressure. I saw reference to the 200 series Racors, they're overkill. They flow 15 to 30gph and the replacement elements are around $30.00 each The 120 series is a basic unit the seperates water and filters at 15gph. Small initial price and less for filters each time.

Pat, that's additional info...
...but I'm not sure it counters any 'argument'. And onboard fuel pumps of all types do fail. Ease of priming aside, redundant fuel pump capability is one of the things I would suggest BO or anyone else consider. No 'shoulds' or 'musts'; just info to be considered. Jack

Electric Fuel Pumps
Jack 1. The fuel pump will pull fuel through the Racor as well as push it through. There has been no change in its performance, and I never have to "refill" the Racor with diesel before I bleed the engine. 2. The electric fuel pump on our boat is necessary because once the fuel tank is less than half full there is not enough siphon head left to move the fuel from the tank through the the Racor and the hoses to the engine. The engine mounted pump has a very low ability to pull fuel through, hence the electric pump. We've learned this through nearly 20 years of working on our C34s. Each boat is different, of course, with different engines. 3. Racor's own literature, noted in the the Related Link in my earlier posting, says to have the Racor ahead of the electric fuel pump. When changing fuel filters and bleeding the engine, all I have to do is open the nut on top of the secondary engine filter, turn on the key and the electric fuel pump, and wait till fuel comes out. I'm done. No manual priming or filling of the Racor is necessary. The electric fuel pump, which I re-piped to be after the Racor, works just fine, and its bowl / filter is now clean and never a source of stoppage of fuel flow. Stu

Sigh...
Stu, I didn't mean to suggest your electric fuel pump wasn't necessary on your boat. As you note, boats differ and your C34 is not the only one that requires an aux pump, that's for sure. It works for you, and that's a good thing. I'm familiar with Racor's recommendation. That led me to set my system up as you describe yours. And as you point out, boats differ; for my Racor (a 500) with an empty bowl, fresh filter and with the fuel below a level that provides a gravity feed to the fuel line, my electric pump wouldn't fill my Racor bowl. Come to find out, my boat is not the only one with this characteristic. I guess some folks here heard me 'pushing' one method over another; I didn't mean to. I think I was trying to a) outline another approach (which may be necessary for some boats; I should have pointed that out), and b) mention the related benefits of having an electric fuel pump in a system despite one not being included by the manufacturer.

Filter Manifold
Does Racor make a dual filter manifold that takes two Mod. 120 filters with a valve to switch between them?

Gary,
I'm not aware of a maniflod using the 120 series. I'm building this setup in a boat this week or next. Email me you address and I'll foreward pics when I get done. Pat McCartin Inland Marine Diesel Buford, Ga imd_ga@hotmail.com

Fuel below
Jack Thanks for your note. Only thing I can think of is to try opening the vent on the top of the Racor housing and see if that lets the electric fuel pump fill the Racor. That danged law of physics keep popping up. Stu
