With all the debate on fuel system varieties along with the pros and cons,
heres what I have and why on my 360-slobuild.
 NO header, 1. burn and fill changes pitch trim constantly  2. manually
requires refilling  too frequently (I have heard several stories of "washing
the windshield" when they forgot to turn off the pump in time.)  3.
automatic refilling too complex  4. in a previous A/C many of the fatals
were caused by ruptured headers (if I really wanted the extra fuel I would
put in a 3 way valve and use the header as the last fuel burned)
Wing fuel out to the tip ribs because 4 hours in the saddle is as much fun
as I can stand.  A baffle rib with flapper valve at BL-60 to avoid unporting
a low tank in the pattern.
I used a friends idea and routed the 3/8 fuel pickup line thru the main spar
webs about BL-54(with Don Goetz blessing) then forward of the main spar to
aft of the nose gear tunnel.  This is the shortest run with the fewest bends
and no low spots for water to accumulate.
A right-left-off fuel valve and probably a super fine fuel filter from
Airflow Performance or Lancair in lieu of a gascolator since I plan to sump
the mains a lot.
This is similar to the stock RV-6 system I am flying with and is as KISS as
I can think of .
