you can buy a chilton or haynes manual at a parts store, or on ebay. Sometimes on ebay they sell the diagrams that are emailed to you in an ebook as well..

SOURCE: have vacume hoses loose on top of motor in a 1989

I'd suggest you go to www.autozone.com and register there, (it's free). Once registered you'll have access to dozens of vehicle repair manuals many having diagrams.

NOTE: I'm not affiliated with autozone, but have registered there and find it useful.

Vacume hose diagram 98 expedition

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't
have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

1997 ford expedition 5.4. no suction on vacum hose pluging into my egr valve.

Follow the hose it runs to the DPFE (egr position sensor). See if hoses are cracked, shrunk or missing. There is an in & out. They need to be a special silicone vacuum hose made for this setup. Usually the replacement silicone vacuum hose is orange. It is available at most autoparts stores. If all sections of hose are ok, either DPFE (egr position sensor) or egr solenoid is bad. There should be a check engine light on for any one of these problems as they each have their own code.

I have a vaccuum leak and am looking for a diagram of the vaccuum lines. Where can I find one? Also, which vaccuum line would affect blower vents on the 03 expedition?

The easiest way to look for vacume leak it to go to the vents and back track to the vacuum supplier. somewhere you should to hear the vacuum leak somewhere. It amazes me how much of fixing cars is do by hearing and not seeing. Sometimes seeing can miss lead you. Let me know if I can help you and more.

I'm not sure if i got the egr vac hose and the fuel pressure reg hose backwards?

The vacum hose that goes to the fuel pressure regulator will have vacum all the time and will come from the in take, the one for the EGR will not have vacum all the time and that hose will come from the EGR control solenoid a black looking solenoid with two ports coming out of it.

2003 ford expedition blowinw out the defrost all the time

It does sound like a vacuum problem. Check vacuum hoses under the hood especially to vacuum reservoir cannister. Sounds like a hose is loose or leaking.
