SKU: RA2010TM-OR

Use this Racor diesel fuel filter element in the 500 series diesel fuel filter. The 10 micron(blue end) is for primary/secondary filtration as the porosity of the filter element is not quite as fine as the 2 micron element. If your boat has duel filters, use a 30 or a 10 micron(blue end) in the filter closest to the tank and a 2 micron(brown end) in the filter after that.
