Yes of course I have, many , many times. I was writing a magazine article on jet fuel for use in model aircraft ft jet engines and wanted to be sure of my facts before publication.
I always knew that the fuel was filtered for particulates but in my research I learned that entrained water cannot be removed by filtration, free water can be but during the pumping process free water is likely to become entrained if the water content of the fuel is below a certain level of ppm. So, I wanted to be sure exactly what that filter was doing.
Just checking, never a bad thing in aviation !
