The vacumm lines are entireley messed up on the jag. So can anyone give a good vacumm diagram?

 

Check if the vaccuum diagram is visible under the hood.

 

Hi, you don't say what year your car is, but a guy called Sean Strong has produced some very good documentation about all things XJS.

Here is his vacuum lines page. Sean's XJS Vacuum lines.

Hope it helps.

 

Thanks for those. I have them under the hood, problem is I dont know what certain things are. Like the line that should be running from the thermal vaccum switch to the air switching valve is disconnected. I dont know what/where the air switching valve is. Also there is NO line running from the vacumm advance on the dizzy. Where does that go?

Anyone have some pictures of some of these vacumm parts that can help?

 

Again, what year is your car ? and is it a V12 or 4.0 6cyl ?

 

86 v12
