Everyone is discussing their header tank type fuel system
designs and only Perry has mentioned a vent to the header
tank. As I understand the black art of fuel systems, multiple fuel
tanks gravity feeding a common header require a vent to
the header tank to ensure uninterupted fuel flow in all
circumstances.

   I don't  claim to be a fuel systems expert, altho by
slavishly copying Burt's basic design with one notable
improvement, my Long EZ has managed to continue to
feed fuel for the last ten years. The only problem I saw
with the stock LE system was that the electric boost
pump (inline with the mech pump, downstream) was the
highest point in the fuel system.  Seemed like a great
place for fuel vapors, so I lowered it so the mech pump
is the highest pt in the fuel system, which of course can't
be lowered without a LOT of work.  :-)

Everybody using plenty of filters and a gascolator?
Andair has two BEAUTIFULLY made gascolators, that are
Porsches to John Deere tractors (HMM, probably where
the AC ones came from) compared to the std AC gascolators.
A bit pricey,but VERY nice and they safety easily plus open
up easily.  Absolutely top quality, still saving up for
mine.  I don't have anything whatsoever to do with these
English folks, just saw them at Sun 'n Fun and spoke with
the son (I think) of the manufacturer.  Wickes has them,
there is the "expensive as heck" one and the merely "pretty
darned expensive" one.  Works of art in aluminium.
