Julia's Problem

[Dan Darst]

Could it be a collapsing fuel line when pulling hard? This happened to me. I
could not squeeze the line to collapse it by hand, but when I took it off,
it stretched like a rubber band. Jeff told me I had a collapsing fuel line,
but with my thick skull it took me two years after that to fix it. Don't
expect to be able to see it because it will be the inside liner not the
outer shell of the line that will be collapsing and restricting the flow. If
this is the problem, it will be most prevalent in hotter temps and harder
pulls.
