Description
Overview
The FASS XWS3002 Extreme Water Separator is a purpose-built diesel fuel filter engineered by FASS Fuel Systems to keep water and contamination out of your fuel system. As the latest generation water separator in the FASS lineup, the XWS3002 is rated at 2 microns absolute, giving it the fine filtration needed to protect injectors, pumps, and other precision fuel system components from the damaging effects of moisture and debris. Whether you’re maintaining a diesel pickup or a fuel-fed SUV, this filter is designed to be a core part of a properly configured pressure-side filtration setup.
Unlike older-style water separators, the XWS3002 does not include a manual drain. That’s because the filter element itself is designed to trap water directly, rather than relying on a bowl that needs to be manually drained down. This design simplifies routine fuel filter change intervals and reduces the maintenance steps typically associated with changing a fuel filter on a diesel system.
Installation & System Compatibility
The XWS3002 is not a standalone, drop-in replacement for every older FASS filter. It is engineered to be used specifically in conjunction with the FASS PF3001 filter. In this updated configuration, the XWS3002 is installed on the pressure side of the fuel system, while the PF3001 is installed on the suction side. If you are upgrading from a previous setup, note that the XWS3002 and PF3001 combination is not interchangeable or compatible with the discontinued FF-3003, FF-3010, FS-1001, or FS-1020 filters. Anyone researching fuel filter replacement cost or comparing an inline fuel filter to a water separator setup should keep this pairing requirement in mind before ordering, since installing the XWS3002 without its matching PF3001 counterpart is not a supported configuration.
For shops and DIYers who are used to running a wix filter finder or similar cross-reference tool when sourcing a diesel fuel filter, it’s worth noting that the XWS3002 is a FASS-specific component tied to the FASS pressure/suction filtration architecture rather than a generic inline petrol filter or universal gas filter change part. Confirming your current FASS filter housing and system configuration before ordering will help ensure a smooth changing-fuel-filter experience.
Fitment
The FASS XWS3002 is designed to fit Truck/SUV applications running a compatible FASS fuel system. It is sold each, and identified under aaiaid FKRH for parts cross-referencing.
