SKU: RA2010SM-OR

Use this Racor diesel fuel filter element in the 500 series diesel fuel filter. The 2 micron(brown end) is for final filtration as the porosity of the filter element is very fine. If your boat has duel filters, use a 30 or a 10 micron in the filter closest to the tank and a 2 micron(brown end) in the filter after that.
