[C320-list] racor filter number

Sat Nov 22 07:21:11 PST 2008

Your RACOR element is probably the R15 series. Most of us seem to run with  
the 10 micron size (R15T) but others have had success with the 2 micron  
(R15S). I just changed a R15S out after 8 months and 220 hrs - very little  
dirt and no apparent backpressure issues.
In spite of success with the R15's, I recently changed to the R20 series  
elements. The R20 is 0.7" deeper but offers more filtering area and 25%  
more dirt retention of the R15 series for the same cost. If you have the  
room under filter, I'd consider that change.
The best prices I've found have been here...
http://www.marinefilters.com/racor_elements.php
and then my local West Marine matched the price.
