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.

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 filter, and drain the water from the separator if a drain is fitted.
- Disconnect the water sensor, if fitted, and remove the old filter with a suitable filter wrench.
- Check that the old gasket came off with the filter. A leftover gasket can cause leaks.
- Clean the mounting surface, and lightly oil the gasket of the new FS1007 fuel water separator.
- Spin the new filter on by hand until the gasket touches, then tighten as specified by the engine manufacturer.
- Reconnect the water sensor, prime the fuel system according to the engine manual, start the engine, and check for leaks.
- Replace the filter at the interval recommended by the engine maker, and sooner when using poor-quality fuel.
