When replacing my PCV valve on my '92 today I broke a vacuum line. Long story short, there are 2 ver small diameter vacuum lines that are routed around the engine back by the firewall. I don't know which attachment goes to which opening on the vacuum tree. Any help would be appreciated.
 






maybe those 2 are for the fpr (fuel pressure regulator) and one is for the heating and ac control system inside the truck.the large one thats attched to the top of the upper intake is i belive for the transmission modulater.

hope this helps.
 






I don't think it matters which port on the vacuum tree they hook up to. When I've had those molded plastic lines break, I've just replaced them with regular rubber vacuum tubing with the appropriate ID.
