9th injector question with pic

I just purchased a 1986 TPI setup to replace my carb system. I tore the TPI set up apart for a good cleaning and I am missing the parts for the 9th injector. Bare with me since I have never seen this before. The pic is labeled #6. Is this the 9th Injector hole? The plug above it was in the hole. It screwsinto the hole with a heavy fuel line on it but it has a hollow center that just passes through into the intake when installed. Did someone just put this in as a plug maybe?

As for the fuel rail: I am guessing #7 is the fuel outlet that goes to the 9th injector - correct me if I am wrong please. The #8 looks like a vacuum line, where would this connect to?

Thanks
Tony

I'll give it a shot...

#6 on top looks to be the drivers side. If so, that's a large hose that goes to the PCV/Breather on the driver side valve cover. (that's how mine is).

#7 is the 9th injector. I have 3 extras if you need one. The injector goes into the hole in the drivers side runner.

#8 is the vacuum line for the fuel pressure regulator. Refer to plenum post for that answer.
