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. For combines that work long hours in the field and often use stored or bulk fuel, regular replacement helps prevent hard starting, power loss and costly injector repairs.

- Spin the new filter on by hand until the gasket touches, then tighten as specified by the equipment manufacturer.
