Bruce, Dale;
There are other things taking place in the fuel systems these days. Alcohol 15% and more is causing lots of problems. But the Vent hose (#6) in the parts manual picture, is the closest dog to the sled.
The recombined fuels they are pumping into your tank can cause the vent tube to shrink, even crack. If it is like mine, it's hard as a rock. Shrink tube will melt, so will vinyl tubing.
Replacing the line will involve removing the tank. Not all that fun but with a beer or two the job is more palatable. Early Coupes are a real bear as the bolts can be troublesome. Later units have the clips and make the job easier. The tanks are interchangeable and after market clips are cheap. Not that the carb couldn't be the culprit, but I can't remember smelling fuel from the carb while behind the wheel.
