Fleetguard Diesel Fuel Water Separator FS1000 Pack of 2 — Stratapore Element, Large Capacity 1-14 UNS Thread

Fleetguard FS1000 is a heavy-duty diesel fuel water separator cartridge (pack of 2) designed to remove free water and protect fuel systems on Cummins Select and Quantum 19L engines.

The FS1000 replaces the older FS1212 and fits applications requiring the larger Stratapore element. Built to Fleetguard specifications, this twin-pack offers a direct-fit service solution for a range of OEM cross-references including Cummins 3329289, Terex 15271319, Caterpillar 2568753 and John Deere RE160384. It combines a high-capacity filtration body with a standpipe and common 1-14 UNS-2B thread so you can swap units quickly during routine maintenance.

How does this separator protect engines during refueling and storage?

The FS1000 physically separates free water from diesel before contaminated fuel reaches injectors or pumps. By collecting water in the lower chamber while allowing treated fuel to pass through the Stratapore media, it helps reduce corrosion and wear in fuel-system components.

• Stratapore filtration media reduces water carryover into fuel lines
• Large outside diameter (93.22 mm) increases capacity for longer service intervals
• Standpipe design isolates collected water for easier draining
• Pack of 2 ensures you have a spare for the next scheduled service

Will the FS1000 fit my engine or machine?

The FS1000 is a direct replacement where the FS1212 upgrade is specified, and it matches common OEM part cross-references. Check thread and height dimensions and your equipment’s parts list to confirm compatibility before purchase.

• Thread size: 1-14 UNS-2B — matches many fuel filter housings
• Overall height: 249.07 mm (9.806 in) — verify clearance in your mounting location
• Outside diameter: 93.22 mm (3.67 in) — for proper sealing and fit
• Cross-references include Cummins 3329289, Terex 15271319, Cat 2568753, JD RE160384

What maintenance benefits and service life can I expect?

The larger element volume and Stratapore media result in increased dirt and water holding capacity, which can extend time between filter changes under normal operating conditions. Regular inspection of the water-collection area and scheduled replacement according to manufacturer intervals will keep fuel-system performance reliable.

• Pack of 2 lets you complete one change and keep a replacement on hand
• Higher capacity OD helps delay saturation compared to smaller elements
• Standpipe simplifies draining collected water during service
• Designed to meet Fleetguard quality and dimensional standards for consistent service life

How do I install the FS1000 safely and correctly?

Installation follows standard fuel-filter cartridge replacement steps: relieve fuel-system pressure, remove the old cartridge, check gasket surfaces, and thread the new cartridge hand-tight to the specified torque. After installation, prime the fuel system as required by your engine maker to remove air pockets.

• Confirm thread engagement: 1-14 UNS-2B matches housing threads
• Hand-tighten until gasket seats, then follow torque spec if available
• Prime and cycle the fuel pump to purge air after replacement
• Dispose of used cartridges and collected water according to local regulations

Who is this for: The Fleetguard FS1000 (pack of 2) is aimed at fleet managers, heavy-equipment technicians, and owner-operators running Cummins Select or Quantum 19L engines or machines listed by the cross-references. It suits anyone needing a direct-fit, higher-capacity fuel-water separator with easy servicing features and a spare cartridge ready for scheduled maintenance.
