No, it flowed freely when the cap was off and trickled to a stop when the
cap was replaced. So I presume there was no way for air to get in to allow
gas to come out. As I said I may have other issues elsewhere with that
engine but right now I'm just trying to figure out this situation which is
only involving the tank and hose. Obviously both the strainer screen and
the shutoff valve under the tank are fine if it was flowing freely with the
cap off.

So I need to know where there is some sort of vent pinhole that has gotten
clogged.

Remove/loosen fuel cap. Test run. If OK tank vent is blocked.
Normally in fuel cap.

Drill a small hole in the cap. The gas caps used to have holes in them
for vents but vapor emissions regulations caused changes to the gas caps
and this is now what happens. You could buy a new gas cap if you are
concerned about the emissions but a tiny hole in the cap will fix it,...
permanently.
