The primary fuel filter on most ISX engines is typically 50-microns.. and would barely filter out sand.. is not good enough.

GET A Davco!.. and install it.

and if the fuel filters are clogging every 1,000 miles.. then you have some other serious issues there... likely algae problems.

I know on my truck, even with B17 Bio diesel, my davco and a 7=micron filter, will last about 15,000 - 18,000 miles or so before the fuel gets to the top of the filter, showing its getting clogged up.
