Is a hose missing?

I have a 1997 TJ (Frankenstein) with a 2.5 in it. I personally believe that the motor is not the original because for a few different reasons. But that's whatever. So yesterday I notice that on the intake manifold right below the MAP Sensor there are a few different vacuum hoses. Well, I have a nipple that is sticking out of the intake manifold that looks like something should be attached to in. In fact it's clean so that leads me to believe that up till recently, something was attached. I took my TJ to a friend tonight that has a 98 with a 2.5 and noticed a lot of differences. So that didn't help much The only thing that he had hook up that I didn't was some tube that ran to something that might be a diaphragm that was connected to the fuel rail.

So the one picture shows the missing hose. It is the brass colored nipple below the MAP Sensor.

Another picture shows my friends motor and the piece that I think that I might be missing. It's the diaphragm looking thing on the fuel rail.

I'm not sure how the pictures are going to turn out. This is my first time uploading any on a forum.

Also, if it helps, I replaced the TBPS and when I asked for a 1997, it was wrong. I matched it to a 1995. Another reason why I don't think that the motor is stock.

So what goes there? A hose? A cap? What? And it does have a vacuum to it. If you stick your finger over it while it's running the motor idles down as it sucks in your finger.
