I'll soon be starting on the fuel system for my 20B Lancair ES.  Not
FWF,
but everything aft of the firewall.  I was planning on plumbing two RWS
electric pumps & filters in parallel, downstream of the fuel selector
valve.

The Lancair manual was written assuming I am doing a typical engine
installation and calls for a Cessna style gascolator.  I have two
questions, for those that are past this point.  1) Is a gascolator of
any
value when using a RWS EC-2 system?  2) Is a boost pump of any value
(upstream of the gascolator).  If you respond, an explanation of your
answer would be appreciated.
Thanks,

Yes, a gascolator serves two worthwhile functions.  Separates out the water
and the screen in it filters out debris before it gets to the pumps.  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.
