New Mustang with major vacuum line problems

[Redfire 05]

I just bought an 86 GT a month or so ago and I've been going through it trying to get it in good driving condition. I've discovered much to my dismay that the previous owners were idiots. Apparently at some time they broke a number of vacuum lines and just capped them off with electrical tape (which didn't work). So now I have a bit of a mess on my hands. There are leaks all over the place and I'm a little overwhelmed because I don't know were anything goes. The vacuum routing sticker is still present under the hood, but I don't know what some of the abreviations mean much less where to find some of it. Obviously I need some help.

So here's what I have for you. Below is a list of the abreviations on the vacuum diagram with what I know and what I don't. I looked through my shop manuals, but not all abreviations were listed. In addition, I took a couple of pictures of a few of the problem areas. Descriptions are below the list. Furthermore, several vacuum lines from the front and rear of the upper intake manifold are broken. I'm not sure where they go either.

List
ABV - ?
ACV - thermoractor air control valve ( I know where this is, but the line is broken and I'm not sure what it plugs into.
CPRV - ?
DMP (SOL V) - ? I assume this is one of the plug ins on the back of the passenger side strut tower, but I don't know which one
DIV - (SOL V) - ? same as above
EGR - Exhasut Gas Recurculation Valve (I know where this is and I only see the one vacuum line coming from the top passenger side).
EVR - EGR valve regulator vaccume solenoid valve (not sure where this is)
FPR - Is this the fuel pressure regulator vaccume line?
MAP - manifold absolute pressure sensor (where is this?)
VCKV - ?
VRDV - vacuum retard delay valve (where is this)?
VRESER - Vacuum resorvior (where is this)?

The first picture is of a little vacuum block on the passenger side fire wall. The arrow to the left is pointing at a line going into the fenderwell. I assume this is part of the hvac controls vacuum routing? The second arrow points to a vaccum line that is broken. I put a peice of vacuum line on it but didn't know where it went. The arrow to the right points to the line coming from the vacuum distribution block on the drivers side of the car (picture 2). It plugs into the port labeled ac.

Please help me and thanks in advance.

Lets see....MAP sensor is on the firewall directly behind the intake manifold. Mounted on a bracket with 2 nuts. EVR is mounted on the backside of the passenger side shock tower. Has a 2 wire plug in and has 2 bolts that hold it down. Round plastic top. VRESER is on the passenger side, between the splash shield and the fender. Plastic fender liner will need to come off to gain access. FPR is indeed fuel pressure regulator. VCKV is the vacuum check valve, passenger side of the firewall towards the hood hinge.
Have you considered looking at a buddy's car or going to a salvage yard to get the correct parts needed?

Thanks a bunch. I'm going to head to the parts store for some vacuum line then see what I can do.

Okay so I took the passenger side splash guard off. There are two things inside with vacuum lines going to them. One is spherical and sits to the back close to the firewall. One is a cylinder and sits in front of the strut. It is about halfway between the firewall and front bumber. Which is the vacuum reservior, and what is the other one (a/c reserve)?

Okay so I've set things up exactly as they look in the provided wiring diagrams (links below) but now my car is idling worse than before. I still don't know the answer to the above question, but I tried the routing both ways and it didn't change things. I believe my problem to be in two areas:
1.) A line, labled a/c runs from the block on the drivers side firewall to the check valve on the passenger side fire wall. This check valve has two ports on it that point down. Can someone tell me where the lines from the two ports pointing down go to?

2. This is where I think the main problem is. Several vacuum lines come from the back of the block underneath the upper intake manifold. One goes to the fuel pressure regulator, one to the MAP, another one (a hard line) was broken on my car. It exits from the block right next to the fuel pressure reg line. I followed the diagram as to the routing of this line, but the car runs really rough. According to the diagram this line splits. One split goes to the EVR, and the other through a check valve. After the check valve the line splits again. One side goes to the vacuum reservior and one splits and goes into the tab and tad. Is this how it works on your car? The two diagrams differ in this routing in one way, one shows and additional split going to the hvac controls. I don't have any idea where this line would go. Where is the line for the hvac controls?

By the way if anyone with an 86-88 GT living in Lubbock, TX would be willing to let me take a look at their car so I can see what your vacuum lines look like I would be eternally greatful.
