How can the vacuum line be reattached to the Fuel Pressure Regulator? There doesn't seem to be a way to attach it. I believe a small piece might be missing from the Regulator but I am not so sure.
Perhaps I need to get a small piece of fuel line to attach to the Regulator then insert the vacuum hose? If so, what size do I need?
I suspect that a piece has broken off and the above may not be possible.
