1986 Mustang GT, 302 H.O. w/5 speed tranny.
After 33 years, most of the vacuum hoses coming from the vacuum tree has rotted, broken, cracked, etc., and now I have a mess I can't figure out. Attached is an actual picture of the vacuum hose diagram on the hood of my car, but it doesn't have all of the vacuum hose connections. I need pictures of what a "VRESER" looks like, "EVR", "SOL V" looks like, or if someone could make a video of the vacuum hose routing on their stock 86 hose routing looks like---for example where the hoses from the vacuum tree goes from, splits off, merges, etc. The car runs, but runs crappy when cold and I've rigged some vacuum hoses to keep it running, but it runs like crap, mileage is way down, etc-----and I know it has something to do with the vacuum hoses and their routing. The picture of the vacuum diagram doesn't show anything about the vacuum tree, and sometimes when I'm driving, all of a sudden the A/C will suddenly just blow outside air for a couple of minutes and then the A/C will kick in again and start blowing cold air. I know part of the vacuum hoses connect to a vacuum hose coming out of the firewall. The car ran fine until the plastic vacuum lines started breaking, rotting, etc.

I know the vacuum lines to the Fuel Pressure Regulator and MAP sensor are set up correctly, but need assistance with the hoses coming from the vacuum tree. THANKS
