I need vacuum diagram for a 1991 Subaru Supercharged. I have just replaced the engine but somehow crossed the lines, both 4wd & diff lock are displayed.
mikedf, did you ever get a vacuum diagram for your 91 that you inquired about on Nov 2011. I have the same problem, maybe you could help me. would appreciate it . I would like to drive mine a little further than the end of my property in something more than idle. thanks Steven
