0101 181 DAF Fuel Filter Water Separator

A Fuel Filter Water Separator is the filter assembly that removes water and moisture mixed into diesel fuel and collects it in a lower bowl, while also trapping solid contaminants such as rust and sediment.

This component serves as the first line of defense in the diesel fuel circuit, positioned between the tank and the transfer pump. It is essential for protecting the transfer pump, injection pump, and injectors from corrosion and premature wear caused by moisture. This part is compatible with various DAF models including the CF 85, XF 95, XG, XD, and XB series, as well as PACCAR PX-7 and MX-13 engines. It is also fitted to Mercedes-Benz, MAN, and Renault Trucks vehicles.

For optimal engine protection, technicians should verify the connection type—whether spin-on or cartridge—along with thread size and sensor compatibility during installation. Regular inspection of the separator bowl and scheduled replacement are critical to maintaining fuel system integrity in heavy-duty environments.
