Bryan,
Why?
If you connect the wings thru a simple T, unbalanced pressurization,
mismanaged filling or a tilted ramp will cause the fuel to move from one wing to
the other with unintended consequences.
A standard built 320 fuel system does not have slosh compartments with
flapper doors built into the wings. Thus, a wing with a low fuel quantity
could easily be un-ported and allow air to be introduced into the fuel
lines. I think you know the result of that happening.
Good Luck,

I want
to run this idea I have past the group.
My current set-up is 1/4" lines coming from my wing tanks to the my
header. Then a 3/8" line feeds my engine. In this configuration I
can only feed the engine from Header only. This is the stock Lancair 320 fuel
system.
I would like to be able to run my engine off my wing tanks if needed but
I don't want to re-plumb the wings with 3/8" lines. Can I connect the
1/4" wing tank lines into a "T" with a 3/8" exit and run the line to the
selector valve? Essentially the wings would not be able to be selected
but they would feed at the same time equally.
Would this idea work? And if so what type of Andair valve would I
need? One with just a Left/Right/OFF And I would have them custom
engrave the bezel to read Wings/Header/OFF
Thanks
