FS19666 Fuel Water Separator
StrataPore™ Media Technology for Cummins QSN14 Engines
Advanced multi-layer synthetic media for superior water separation.
Direct 1:1 replacement for Cummins 4345001, tuned for QSN14 series.
Rated flow of 5.70 L/min (1.51 gpm) for consistent power delivery.
Built to withstand intense vibration of large-displacement diesel systems.
For high-displacement engines like the Cummins QSN14, even microscopic water droplets or fine particulates can lead to catastrophic injector failure and fuel pump cavitation. Standard filters often lack the structural depth to handle the intense fuel flow required by 14-liter engines, resulting in frequent downtime.
How the FS19666 Fuel Water Separator Works
The FS19666 utilizes , a multi-layered synthetic media. As fuel passes through, the unique fiber structure coalesces tiny water droplets into larger ones that settle at the bottom, while trapping silt and rust within its layers. This ensures that only chemically pure, "dry" fuel enters the high-pressure injection system.
Why Select Our FS19666 Solution?
- StrataPore equivalent media protects against "soft" particles that bypass lower-quality filters.
- OEM-Standard Testing:ISO 19438 specifications for efficiency across the service life.
- Precision-machined 1.25-12 UNF threads prevent air ingestion and erratic idling.

- Cummins-powered standby gensets
- Heavy-duty earthmoving equipment
A: StrataPore is synthetic multi-layer media with finer filtration and higher dirt-holding capacity, specifically designed for small abrasive particles that standard cellulose paper cannot trap.
A: Typically 250-500 hours as per Cummins manuals. Separators should be drained daily if water is present and replaced immediately if differential pressure rises.
Is this filter compatible with high-sulfur diesel?
A: Yes. Materials used in the FS19666 are resistant to corrosive components found in high-sulfur or lower-grade fuels in specific export markets.
Adhering to rigorous industrial standards. Every FS19666 is pressure-tested and vacuum-sealed for zero-contamination global transit.
