inline tube proportioning valve failure

Had the same leak issues. I found rebuild kits at Muscle car research. So far no new leaks.
I still don't trust the repop part as it has a plastic disc in place of an original metal piece. If I had an original part I would have no problem rebuilding it using parts from Muscle car research.
