Housing and Engine Compatibility
The FS20385 is a cartridge element, not a complete spin-on filter. It fits the Fuel Pro 485 housing only, so confirm your housing model before ordering. When the truck has this housing, cross-reference data lists it for:
- Detroit Diesel DD13, DD15 and DD16 engines (2008 and later)
- Cummins ISX12 and ISX15 engines (2010 and later)
- Cummins X15 engines (2017 and later)
- Trucks using these engines, such as the Freightliner Cascadia and Coronado
Fit depends on the housing installed on the truck, not only on the engine. Send us the OE number from your old element, 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 FS20385 Fuel Water Separator
- Factory-Direct Supply: IXIN manufactures filters in its own factory in Linxi County, Hebei. You deal with the manufacturer, not a trading company.
- Wide Cross-Brand Coverage: One FS20385 fuel water separator replaces several brand numbers, which helps distributors simplify inventory across Detroit Diesel, Baldwin and Donaldson references.
- 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.
To avoid cross-reference mistakes, read our fuel filter cross reference guide before placing a bulk order.
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 FS20385 fuel water separator 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.
