FASS Titanium Series Fuel Filter Combo Pack XWS-3002XL & PF-3001XL - Replaces FF-3003, Extreme 2-Micron Water Separator

This FASS Titanium Series combo pack pairs the XWS-3002XL 2-micron extreme water separator that traps over 99% of water without a drain and the PF-3001XL 144-micron particulate filter. It reduces cavitation, boosts flow, quiets the system, and removes large particulates, perfect for FASS fuel system owners needing reliable maintenance.

  • Traps over 99% of water at 2 microns absolute with no drain needed for hassle-free maintenance
  • Reduces cavitation dramatically using 144-micron particulate filter on suction side
  • Boosts fuel flow properties for optimal FASS system performance
  • Lowers overall sound output for quieter operation
  • Removes large fuel particulates to protect your engine

Exceptional water separation eliminates drain maintenance. Enhances flow and reduces noise for better system efficiency. Convenient dual-filter pack simplifies FASS upkeep.

Requires specific suction/pressure side placement per diagram. Incompatible with older FASS filters like FF-3003 or FS-1001. New design mandates using both filters together only.

Welcome to the premier destination for FASS Diesel Fuel Systems fuel filters, where diesel enthusiasts find top-tier solutions for maintaining peak engine performance. This category spotlights the FASS Titanium Series Fuel Filter Combo Package (XWS-3002XL / PF-3001XL), a direct replacement for FF-3003, engineered to deliver exceptional filtration and reliability for heavy-duty diesel applications.

Why Choose FASS Diesel Fuel Systems Fuel Filters?

FASS Diesel Fuel Systems has built a stellar reputation in the diesel aftermarket for crafting high-quality fuel delivery components that outperform stock options. Known for their innovative designs, these fuel filters stand out with advanced filtration media that captures contaminants down to micron levels, preventing injector damage and extending engine life. Whether you're towing heavy loads or navigating rugged terrains, FASS products ensure consistent fuel flow and reduced downtime.

What sets FASS apart is their commitment to durability—filters feature robust construction with corrosion-resistant housings and high-capacity elements that last longer than generics. As part of our extensive Filters collection, FASS offerings integrate seamlessly into comprehensive maintenance routines for trucks and SUVs.

Spotlight on the Titanium Series Fuel Filter Combo Package

The star of this category, the Titanium Series Fuel Filter Combo Package (XWS-3002XL / PF-3001XL), combines a water separator and high-efficiency filter in one convenient kit. This combo replaces the FF-3003 while upgrading your system's capabilities. The XWS-3002XL excels at separating water from fuel, a critical feature for diesel engines prone to contamination, while the PF-3001XL provides absolute filtration to safeguard injectors and pumps.

Ideal for Cummins, Duramax, and Power Stroke engines, this package supports flows up to demanding levels without restricting performance. Its titanium-inspired durability means fewer changes and more miles between services, making it a smart investment for fleet operators and off-road adventurers alike.

What to Look for When Shopping FASS Diesel Fuel Filters

Selecting the right fuel filter involves prioritizing micron rating, flow capacity, and compatibility. FASS excels here with filters rated for 2-5 microns, far superior to many OEM specs. Consider your vehicle's fuel system pressure and annual mileage—higher-capacity units like the Titanium Series suit high-mileage trucks.

  • Micron Efficiency: Ensures ultra-fine particle removal for cleaner fuel.
  • Water Separation: Prevents corrosion and microbial growth.
  • Build Quality: Aluminum or composite housings resist diesel's harsh environment.
  • OE Replacement: Direct fit minimizes installation headaches.

Installation and Maintenance Tips

Installing the Titanium Series Combo is straightforward with basic tools—typically a 1-inch wrench and filter wrench. Drain old fuel, replace elements, prime the system, and bleed air for a leak-free start. Maintenance every 15,000-30,000 miles keeps performance optimal; inspect for debris during oil changes.
