Binding of water condensate - diesel fuel

Diesel fuel has poor properties to absorb water condensate and carry pollutants with it. Therefore, it is absolutely necessary to adhere to the prescribed replacement interval of the fuel filter or to change it after a long trip outside of Europe. Unfortunately, the previously used dehydration valves in modern diesel filters are increasingly becoming out of fashion, so that the filter housing is no longer dried and the condensate is no longer drained.
