Thanks again for your reply. I just replaced the valve with a new one from MB. The old diaphragm was completely torn, and the pin on the bottom was seized with petrified fuel sediment from 15 years of sitting. Even after cleaning and soaking in carb cleaner for days, I wasn't comfortable with the freedom of movement in the pin. The carbs were professionally cleaned and rebuilt, and I have installed an in-line fuel filter just prior to the mechanical pump.
Here a couple of photos of the way mine is set up. I know it's incorrect, but the engine is running very well right now, so I am hesitant to fiddle with it.
