Fuel Water Separator Filter FS1285
The Fuel Water Separator Filter FS1285 is a heavy-duty, high-capacity spin-on treatment element designed for primary diesel fuel purification. Utilizing a proprietary multi-layer hydrophobic cellulose-synthetic blend media, it forces emulsified water droplets to coalesce and drop out of the fuel stream while capturing rigid abrasives such as silica, rust, and tank sediment. Encased in an impact-extruded steel canister, this element maintains structural integrity under heavy hydraulic pulsing, ensuring continuous fuel compliance even in highly contaminated field operations.

Failing to replace a compromised primary filter or using low-tier alternatives poses severe risks to high-capacity diesel engines:
- Seal Lubrication: Clean the filter header mounting surface thoroughly. Apply a thin coating of clean engine oil or diesel fuel to the clean rubber gasket prior to mounting; do not use grease, which can attract contaminants.
- Torque Protocol: Spin the canister clockwise until the gasket makes contact with the base plate. To prevent over-compression and thread binding, tighten the filter an additional 3/4 to 1 full turn by hand. Do not use strap wrenches for tightening.
- Water Purging Maintenance: For applications running in high-humidity zones, check the lower sump or water collection bowl at every pre-shift inspection. Open the drain valve to clear water accumulation before it reaches the pleat level.
