Does anyone have a parts breakdown or diagram of the vacuum lines?  All of my vacuum line fittings are dry rotted and I want to replace all of them. I'm going to call the dealer today but in the past they always seem to be a little lost when it comes to the diesel trucks.

Honestly, when I started replacing mine I just used regular rubber vacuum line. It's cheap, just cut it to whatever length you need. Just replace one line at a time.

1999 Dodge's are pretty simple.

 

Vacuum goes from the vacuum pump to the cowling. Then routes over to the passenger side for HVAC controls. There should be a second line that heads down to the transfer case. If you have a exhaust brake then you could have a 3rd port on the passenger side for the exhaust brake. Routing and tubing is up to you. I would be really worried about getting factory parts. I would look at where the tubing is routed and run new rubber hose or plastic line. Most of all this stuff could be had a NAPA store. Like on my 1996 Dodge I was cheesy and bought cheap vinyl tubing and replaced all the plastic tubing. This time a around I'll most likely do Air Brake line and a bit of rubber for nipples. Re do the entire routing because I think I can do better.

Great minds think alike. I had some scrap air brake hose at the shop that worked just fine. I picked up the flexible connectors at Advance Auto.
