Genuine Fleetguard FS1000 Fuel Water Separator (Pack of 6) | OEM Spin-On Filter for Cummins 3329289

Stop water contamination before it reaches your high-pressure injectors. The Genuine Fleetguard FS1000 (Pack of 6) is the industry-standard "Spin-On" protection for Cummins engines. Engineered with patented Stratapore™ media, this filter is designed to remove 95% of free water and 90% of emulsified water. Don't risk your engine's fuel pump on generic alternatives—stick with the original equipment manufacturer that Cummins trusts to keep heavy-duty engines on the road.

🧠 WHY THIS MATTERS

At Valtrix Powertrain, we know that in the world of heavy-duty diesel, fuel purity is non-negotiable. The FS1000 is a mission-critical component for Cummins C, L, and M series engines. Unlike standard cellulose filters, Fleetguard’s Stratapore™ media uses multiple synthetic layers to provide higher particle-holding capacity and superior durability against fuel surging. Purchasing this 6-pack ensures your fleet maintains a consistent service interval, preventing the "pitting" and corrosion that lead to expensive injector replacements.

❓ FAQ

Q: Is this a primary or secondary filter? A: The FS1000 is typically used as a Primary Fuel Water Separator. It is designed to remove the "heavy" water and debris before the fuel reaches the secondary "polishing" filter.

Q: Does this filter include the drain valve? A: Yes, the FS1000 comes with an integrated twist-drain at the bottom for easy removal of collected water between service intervals.

Q: Can I use this on non-Cummins engines? A: Yes, as long as your filter head uses the 1-14 thread pitch and can accommodate the height of the FS1000, it is a high-efficiency upgrade for many industrial diesel applications.
