Out the fill vent.

I don't think much fill-replacement air is going to make it through
the tank ventilation system, which goes through the fuel/vapor
separator, a long line of 5/16" tubing and hose, and a charcoal
canister, the output of which is connected to the manifold. Compared
to the half-inch fill vent line that goes to the vent ring on the
fillter, I don't expect much air to be served by the tank ventilation
system.

Yeah, y'all are probably right. But I sure do hate to give up even a little
bit of help. I've washed the side of the GMC with gasoline so many times
it's a miracle the beltline trim is still glued on.
