Have a used but working stock appearing fuel pressure regulator that needs to go. It works and has an Allen screw at the top of it for the adjustment. 40 shipped to your door. 785 806 2331. Pm of text
not trying to cause an issue but I don;t believe that is one of my old style regulators years ago a company called bowling green customs out of georgia sold a version like this where the screw was in the vacuum port on the top. From what I recall.
versions we did early on had a seperate adjustment screw.
