Addition to Don Skeele post.
It is interesting with regard to transfer rate.  My transfer is at a rate of
.45 gal. per minute from each wing tank.  I have tested this over many hours
of timing so I know it is right.  I suppose all systems will vary depending
on tube diameter, curves, venting, lifting distance etc.  I have a Facet
pump for each wing to the header tank.  Out of habit I transfer one wing at
a time.  I'll go 5 min. one side, then 6 min. the other side for 5 gallons
each 11 minutes.  I had an unreliable header fuel gauge for a long time so
the slight imbalance gave me assurance that the fuel was, in fact, going to
the header tank, or somewhere.  I have finally installed a clear
polyethelene line vertically on the panel to show fuel remaining in the
header.  Additionally, I exposed the two clear lines from the wings for
about an inch or so below the panel so I can see the bubbles of transfer or
empty tank bubbles.  I make it a habit to log the pump running times.  It is
just another check, plus it keeps the brain (what is left of it) attentive,
alert, watching.  I keep 7 to 10 gallons in the header.
