FASS Fuel Filter Pack XL — PF3001XL & XWS3002XL two-filter kit with water separation & particulate protection

The FASS Fuel Systems Filter Pack XL is a two-filter service kit containing one XWS3002XL extreme water separator and one PF3001XL particulate filter to maintain and upgrade compatible FASS fuel systems.

This kit pairs FASS’s latest water separation and particulate filtration components into a single, ready-to-install pack for workshops and DIY mechanics. The XWS3002XL is an enhanced extreme water separator rated to 2 micron absolute and designed to capture over 99% of free water, eliminating the need for a drain, while the PF3001XL is a 144-micron suction-side particulate filter that reduces cavitation and protects the pump and engine from larger debris. Note: the new filters must be used together and are not compatible with older FF3003/FF-3010 or FS1001/FS1020 filter models.

How does this pack improve fuel system reliability?

Combining a high-efficiency water separator with a suction-side particulate filter targets two key threats to diesel fuel systems: free water and coarse contaminants. By removing water and larger particles before they reach the pump, the pack helps preserve pump life and maintain steady flow characteristics under load.

• XWS3002XL removes over 99% of free water with a 2-micron absolute rating.
• PF3001XL captures 144-micron particulates on the suction side to reduce cavitation.
• Joint use minimizes pump stress and sound output from aeration-related noise.

What changes when replacing older filters with these XL versions?

The XL components require a different placement compared with some discontinued parts: the XWS3002XL is installed on the pressure side of the pump while the PF3001XL sits on the suction side. Installing them as a matched pair ensures proper filtration sequence and prevents compatibility issues with older filter elements.

• Do not mix XWS3002XL or PF3001XL with FF3003/FF-3010 or FS1001/FS1020 models.
• Follow FASS system layout: suction-side PF3001XL, pressure-side XWS3002XL.
• Designed for straightforward retrofit and routine service intervals.

What practical benefits will I notice after installing this filter pack?

Expect reduced fuel contamination events, smoother pump operation, and quieter running thanks to fewer cavitation incidents. The water separator’s high capture efficiency also reduces the need for manual draining, simplifying maintenance for busy shops or homeowners.

• Less frequent water-related maintenance due to superior separation efficiency.
• Lower pump noise and improved flow stability from the suction-side particulate filter.
• Quick swap-in installation for servicing FASS systems.

Who is this for: The FASS Fuel Systems Filter Pack XL is made for professional repair shops, diesel fleet maintainers, and DIY enthusiasts who want a single, compatible kit to service FASS-equipped vehicles. It’s ideal when replacing discontinued filter models or when upgrading to the latest water-separation and particulate protection standards—provided you use both PF3001XL and XWS3002XL together as directed.
