Housing and Application Notes
The FS20172 is a cartridge element, not a complete spin-on filter. It is used inside a compatible filter housing, so the housing on your truck decides whether it fits. Cross-reference data lists it for:
- PACCAR trucks (OE numbers K371010, K371011 and K371029)
- Cummins X12 and X15 engines (2017 and later)
Fit depends on the housing installed and the engine version. Send us the OE number from your old element, and your truck model and year, if you are not sure.

Why a Fuel Water Separator Matters
Water and dirt in diesel fuel can damage injectors and high-pressure fuel pumps. A fuel water separator removes free water and fine contaminants before the fuel reaches the engine. Regular replacement helps prevent hard starting, power loss and costly injector repairs, especially on long-haul trucks that refuel from different sources.
Why Choose IXIN’s FS20172 Fuel Filter
- Factory-Direct Supply: IXIN manufactures filters in its own factory in Linxi County, Hebei. You deal with the manufacturer, not a trading company.

- Cartridge Design: Replacing only the cartridge keeps service simple, and the housing can stay on the truck.
- Customization Available: We support customization of filter paper quality, metal thickness and packaging for your market.
- Fast Delivery: In-stock items usually ship in 5 to 10 days. Made-to-order items take 15 to 45 days, depending on quantity.

Installation and Maintenance Notes
- Switch off the engine and let it cool. Close the fuel shutoff valve if fitted.
- Place a drain pan under the housing, and drain the water from the separator if a drain is fitted.
- Open the housing according to the manufacturer’s instructions, and remove the old cartridge element.
- Clean the inside of the housing and check the gasket and seals. Replace worn seals.
- Install the new FS20172 fuel filter cartridge, making sure it seats correctly in the housing.
- Close the housing and prime the fuel system according to the engine manual.
- Start the engine, check for leaks, and replace the filter at the interval recommended by the engine maker. Replace sooner when using poor-quality fuel.
