I used

a single EFI type filter after the pumps to catch the really fine

stuff.

Unless you have a system like Ed Andersons,  the boost pump is not

needed if

you keep the pumps at or below the fuel tank level.

 A basic question that I have is how fine a filter does one need?  100

micron, 30 micron, 10

micron.  The screen in the gascolator I have is said to be >100 microns.

Anything smaller would

easily pass through our high flow injectors; so . . .

Are you wondering if any further filter is needed?  Don't know for sure but
the industry has obviously settled on the need for a filter down stream of
the pump.  This seems like a good idea in the event that the pump sheds some
debris which could block the injectors.
