I did a search and didn't find anything. My car is now finally running after 3 years and I need a diagram to put the vacuum lines back factory so my buddy can tune it. It had two grainger valves worked in. My buddy doing the tuning said those need to be taken out. Any help is appreciated.

If Jim Tapp doesn't see this soon, send him an email and GOOD pictures of the vacuum lines and location points. I used to contact him sometimes - he should be familiar with my car, as well as Ned's.

BTW, Jim Tapp is "Protanus"

I know this is a late reply, and I will prolly get bashed for bringing up a dead topic but I do have 1 diagram that might help you...
