Fleetguard FS20172 Fuel Water Separator 6-Pack Cummins X15 PACCAR MX13

Fleetguard FS20172 Fuel Water Separator 6-Pack — Genuine OEM 10-Micron Filter for 2017+ Cummins X15/X12 & PACCAR MX-13/MX-11 Engines

The Fleetguard FS20172 6-Pack is a case of six genuine Cummins Filtration StrataPore cartridge fuel/water separators rated at 10 microns, specifically designed for the PACCAR K37-1029 fuel housing platform found in 2017 and newer (EPA17+) Kenworth and Peterbilt trucks. This filter directly replaces PACCAR OEM part number K37-1029 and supersedes the older K37-1010, K37-1011, and K37-1012 cartridges.

The FS20172 fits trucks running BOTH Cummins engines (X15, X12, ISX15, ISX12) AND PACCAR engines (MX-13, MX-11) — making it the correct fuel/water separator for the majority of 2017+ Kenworth and Peterbilt Class 8 trucks regardless of engine choice. The StrataPore coalescing media delivers 98% emulsified water separation and fine particulate removal, protecting high-pressure common-rail injectors from water damage and contamination.

Buying a 6-Pack covers a full year of service intervals for a single truck, or one service cycle for a small fleet. Trusted by fleet managers, owner-operators, and diesel shops running Kenworth T680, T880, W990 and Peterbilt 567, 579, 389 trucks.

These three filters are NOT interchangeable — they fit different fuel housing platforms. Check your truck's fuel housing part number to determine the correct filter.

When to Replace

Replace at each scheduled service interval or when you observe reduced fuel pressure, extended cranking, loss of power under load, water-in-fuel warnings, or fuel system fault codes. The 10-micron StrataPore media captures fine contaminants that coarser filters miss, extending injector life on modern high-pressure common-rail systems.

What's Included

6x Fleetguard FS20172 Fuel Water Separator Cartridges with O-Rings — packed in one factory-sealed Fleetguard box. Each cartridge is genuine Cummins Filtration, not aftermarket or repackaged.

Why Choose Genuine Fleetguard for Your Kenworth or Peterbilt?

The FS20172 is engineered by Cummins Filtration specifically for the PACCAR K37-1029 fuel housing. The StrataPore coalescing media is calibrated for the flow characteristics and pressure specifications of both Cummins X-Series and PACCAR MX engines. Aftermarket cartridges may physically fit the housing but often use media with different water separation efficiency, resulting in water passing through to injectors. On Cummins X15 and PACCAR MX-13 engines where injector replacement costs $8,000-$18,000+, genuine Fleetguard filtration is the most cost-effective protection available.
