Can anybody tell me or show me a diagram of where the vacume lines go. Mine is missing many of them and I have not been able to get them on correctly.thanks

there should be a vacuum diagram under the hood of the car, however there are only a few that you really need

off the boot which connects to the throttlebody you will have a line which goes into a AAV, on the other side a line which connects to the manifold after the throttlebody. this same line will also have the brake booster connected to it. the only other line which you need to have connected is on the side of the throttlebody right at the butterflies this small line goes to the vacuum advance on the side of the distributor.

that is all that is actually needed for the car to run.

This is all I have on mine.
The crankcase breather will connect to the air box on US cars.

Hey Aussie, I dont understand why you have the black line which the brake booster taps into running back almost to the fual dizzy, that would be letting air by the throttlebody and preventing you from having the proper idle, unless there is a restrictor in that line.

The 'Y" piece has to be put in the right way so I found out when I replaced hoses. (Had little or no brakes)
