Hang on, diesel is not hygroscopic, hydrocarbon chains are hydrophilic in the same way that oil repels water. The diesel filter is nothing magical, think of it as a decanter for diesel, since water will settle below the lower density diesel in the fuel tank.
So why do diesel cars get water into their fuel system much more than petrol ones then.
