[C320-list] FW: Re: racor filters

[Karl Mielenhausen _/)]

Koen,

This has been a mildly controversial topic over the 2 years that I have been following this list. Indeed  the S = 2 micron, the T = 10 micron, and the P = 30 micron. 

One school of thought in to use the 10 micron here as your primary filtration and then the 2 micron final filtration on the engine (mine is Yanmar P/N 104500-55710). The logic is that you would be less likely to restrict the flowrate of diesel fuel through the Racor which could starve the engine for fuel, especially at higher rpm's.

Other Yanmar mechanics have told me that this precaution is unnecessary, as the Racor elements have plenty of flow capacity, and running the 2 micron as the primary is no problem for the fuel pump to handle. Also, if you do that and you do begin to plug, you should only have to replace the 2 micron Racor element and not the final filter. This could be a consideration out on the open seas!!

A search of the discussion list archieves may yield other opinions.

It was me who asked about the difference. But I'm<br>still not clear as to what the difference means? Does<br>it mean that the 2 micron filter is a better one as it<br>filters down to 2 micron particles? So the R24S should<br>be the more expensive one?<br><br>Thanks, Koen<br><br>----- Original Message ----<br>From: jsever1 <jsever1 at cox.net><br>To: C320-List <c320-list at catalina320.com><br>Sent: Saturday, October 7, 2006 8:53:47 PM<br>Subject: Re: [C320-list] exhaust elbow question--racor<br>filters<br><br><br>Someone asked a while back about the difference<br>between the R24S and R24T.
