Either the fuel is mostly clean or it is trash.

Folks attempt to get clean fuel as the price between house fuel and off road diesel is low , they go to a marina and pray..

I think the fuel system should be the chooser of filter size.

For an engine with virtually no returned fuel , the staggered 30-10-2 works fine .

AS the filters will be cleaning unknown out of the fuel.The filters must be EZ to replace , out of the ER is best.

For a DD or other engine that returns most of the filtered fuel a 2 in the primary works just fine.

The ability to continue should a filter in the pair plug ,just by switching a lever is great.

After a few hours all the fuel in the tank will have been filtered multiple times .

The std on engine 10 has little trouble cleaning the few chunks that get past the 2., so lives a long life.
