OK, how about a really far out SWAG on this one; when you put the
clothespin on the line, it isn't strong enough to cut off the gas, but does
change the diameter and shape of the line, creating some sort of Bernoulli
effect, which makes the gasoline more able to either break up or move past
the "vapour" locked portion? It's almost worth getting vapor lock just to
try it out. Perhaps I should get some transparent fuel line (where? You
tell me...) and do an experiment in the interest of science.
