[C320-list] Seeking tip on fuel filter

[Dave Hupe]

 Jack-
Here is detailed information that likely applies to your Racor fuel/water separator setup (Marine Model 220RMAM, 30gph) including spare parts such as a plastic bowl:http://www.parker.com/parkerimages/Racor/7238%20Rev%20D%20(200%20Series).pdf

I use an R24T (10 micron) filter element on the separator unit and a secondary 2 micron spin-on filter on the engine itself.  I check the plastic bowl frequently for possible water collection.  However, you may elect to use a recommended, more costly  R24SUL ("marine") filter element that has "aquabloc" media with enhanced water separation:http://ph.parker.com/us/en/marine-replacement-filter-element-spin-on/r24s-ul
You might instead have this 215R unit (15gph) like a friend who owns a newer (2000) Cat320:https://www.fisheriessupply.com/racor-215r-series-diesel-spin-on-fuel-filters-with-clear-bowl
