The new more efficient Extreme Water Separator (now located on the PRESSURE side of the pump) is rated at 2 microns absolute. It no longer has a drain is because the filter element itself traps the water. The new XWS-3002XL MUST be used in conjunction with the PF-3001XL. The new filters cannot be used in combination with the FF3003/FF3010 or FS1001/FS1020. The new Particulate Filter (now located on the SUCTION side of the pump) is rated at 144 microns and will drastically reduce cavitation, increase flow, reduce sound output of the FASS System, and removes larger fuel particulates.

• The new style water separator (XWS-3002XL) is now placed on the PRESSURE side of the pump.
