Quick question (hopefully). Putting a new power steering pump in my 90 Comanche, 2.5l. When I disconnected the old PS pump high pressure line (top finger) this is what it looked like. New pump looks like bottom finger. I assuming i just need to take the nipple with the o-ring off the old high pressure line, then that long cylinder before the bigger nut will go in the pump, right? Any help is appreciated! Thanks

This issue is on a 1990 MJ 4.0 l6 automatic with just under 165k miles. I went to do my emissions test today for Colorado and the truck failed due to high NOx levels. After researching what causes high NOx levels I found that the EGR is supposed to reduce them and that may be my problem. Upon inspection of my vehicle I noticed that my EGR valve is not hooked up to any vacuum lines, the solenoid is no where to be found and most of my vacuum lines appear to be misplaced or missing. I was using the diagram on the firewall for reference on how the lines are supposed to be run. Has anyone else run into this with their Comanche? Where would I start to try to restore the vacuum system to its original state? I included a crude drawing I did to illustrate how the vacuum lines are currently run in the truck. I would greatly appreciate any help I can get. Thank you in advance. This is the diagram on the firewall. This is my illustration of how the vacuum hoses are currently connected I have a few more photos, here is a link to the slide show of all the photos I have: I can take more of specific parts if need be. Thank you again!
