What does the path of least resistance look like for 10 gal per hour of air through a 3/8" line?  If we were talking honey or motor oil or something ... but AIR?
I don't think we can measure anything that small ... Jim S.

Jim, Air and fuel flow will do a path of least resistance. If you 't' the line the flow will go toward the easier tank. If you run separate vents it can't do that.

I've never quite understood how that can be important (BTW, in the line 
from the "T" to outside, there's a check valve that will vent to cabin 
air in case some critter takes up residence in the end of the vent and 
stops it up.
Forgot to mention that ... Jim S.
