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.
