Working on part A12-14736-003. Trying to understand how to plug the grey tab which isn't being used. I still have the black golf tee looking piece from my old manifold but it don't just go into the valve. any help is appreciated
You need a plug for that connection as well. The only option if you don't have as a temp until you get one is to take a piece of air line and put it into the connection and then crimp it and put vice grips or something on the crimp to prevent it from leaking until you get a plug.
