It could probably be argued that because all the tanks are interconnected
with the fuel being pumped to the header and the engine feeding from the
header only - that there is only one tank, and it does have a gauge.

In Glasairs there are 2 tanks - header and main, each with its own gage.

  This topic is probably beat to death but Im not sure anyone ever clarified
it.
  RE: equipment for DAY VFR flight.
  
FAR 91.205   (9)  Fuel Gauge indicating the quantity of fuel in each tank.
  
  I am still trying to figure this out because I do not have fuel probes in
my
wing tanks. I do have one in my Header tank.  But according to the rule it
states that a gauge is required for EACH tank.
  
  How has everyone been meeting this requirement without gauges for the wing
tanks?

[Bryan, a number of folks have reported that they received their
airworthiness
certificates and regularly operate their aircraft with only a header tank
gauge.  Given that the FARs are couched in so much typical legalese, it is
no
wonder that so many interpretations exist.  If you look at 14CFR Part 91.205

it outlines the required equipment for "powered civil aircraft with a
standard
category U.S. airworthiness certificate", which begs the question of whether

or not our amateur-built experimentals qualify, because in another FAR
standard airworthiness certificates are not issued to experimentals... they
each receive a special airworthiness certificate.  (There is a good article
at
the SportAir site
(http://www.sportair.org/articles/Rules%20&%20Regulations%20of%20Airplane%20
Building.html)
that is well worth reading.)  Additionally, you might want to peruse the FAA

Advisory Circular 20-27F (get it from either the FAA or EAA sites)... lots
of
good information in there as well, and it suggests that our experimentals
_are_ governed by FAR 91.205 (at least, that's how I see it) which, asyou
know, says that each tank requires a fuel guage.  However, Advisory
Circulars
are only that, advisory, and their information must be interpreted according

to 14CFR, so we are pointed to the regulations once again, and need to don
our
lawyer hats to understand them.

I know that we went through this recently, but I, too, would appreciate a
well-presented explanation of why or why not the sections of 91.205 apply.
