Bryan,

Why?

If you connect the wings thru a simple T, unbalanced pressurization,=20 mismanaged filling or a tilted ramp will cause the fuel to move from one win= g to=20 the other with unintended consequences.

A standard built 320 fuel system does not have slosh compartments with=20 flapper doors built into the wings. Thus, a wing with a low fuel quant= ity=20 could easily be un-ported and allow air to be introduced into the fuel=20 lines. I think you know the result of that happening.

Good Luck,
