FASS Fuel Filter Combo Pack XWS-3002XL + PF-3001XL — 2µm Water Separator & 144µm Particulate Upgrade

The FASS Titanium Series Fuel Filter Combo (XWS-3002XL + PF-3001XL) is a two-piece replacement pack that removes water and large particulates to protect your diesel fuel system.

Engineered as a direct upgrade to older FASS filter models, this combo pairs a 2-micron absolute extreme water separator with a 144-micron suction-side particulate filter. Together they improve fuel delivery, reduce cavitation, and trap water and large debris so your lift pump and injectors operate more reliably. The two-piece set is sold as a convenient pack for shops or vehicle owners who want straightforward maintenance for FASS fuel systems.

How does the XWS-3002XL remove water without a drain?

The XWS-3002XL uses a fine 2-micron absolute filter element that captures water within the media itself, eliminating the need for a manual drain. Because the element retains over 99% of water contamination, routine draining is no longer necessary, simplifying service intervals.

• 2-micron absolute rating for high-efficiency water capture
• Filter element holds the trapped water, removing a drain point
• Designed to replace older separators like FF-3003/FF-3010 when used with PF-3001XL

Why pair the PF-3001XL 144-micron particulate filter on the suction side?

Placing the PF-3001XL on the suction side reduces the volume of large particles entering the pump, which lowers cavitation risk and improves flow dynamics. The coarse 144-micron rating stops bigger contaminants that could wear pump components and disrupt fuel delivery.

• 144-micron media catches large debris before the pump
• Reduces cavitation and pump noise for smoother operation
• Helps maintain consistent flow and extends component life

What installation changes should I know compared to discontinued filters?

The new pair is not compatible with older filter housings and must be installed with the XWS-3002XL on the pressure side and the PF-3001XL on the suction side. Check the location diagram printed on each new filter to confirm proper orientation and avoid cross-compatibility issues.

• XWS-3002XL goes on the pressure side of the pump
• PF-3001XL mounts on the pump suction side
• Not compatible with FF-3003/FF-3010 or FS-1001/FS-1020 filters

What measurable benefits should I expect after swapping to this combo?

Customers commonly see quieter pump operation and improved fuel flow due to reduced cavitation and fewer large particles reaching the pump. Because the water separator retains moisture in the element, routine service becomes simpler and less mess-prone.

• Lower system noise from reduced cavitation
• Improved fuel flow characteristics and pump efficiency
• Cleaner fuel delivered to downstream components and injectors

Who is this for: This FASS Titanium Series Fuel Filter Combo is aimed at diesel owners, fleet managers, and repair shops that service FASS-equipped systems and want a modern replacement for discontinued filters. It’s ideal when you need a compact, maintenance-friendly solution that improves fuel quality, reduces pump stress, and fits into standard FASS service routines.
