Vacuum Diagram 93' Cobra

See http://www.veryuseful.com/mustang/tech/engine/

Keep in mind that the vacuum system really doesn't care where you plug the lines in. Just don't leave any on the lines open & uncapped.

Here's a list for the Explorer/GT 40 which uses the same lower.

Vacuum line connections:
One large vacuum line from the upper front goes to the carbon canister

One large vacuum line from the rear goes to the vacuum tree.

One small line in the front feeds the Smog pump solenoid control valves on the rear of the passenger side wheel well..

One small line in the rear goes to the fuel pressure regulator.

One small line in the rear goes to the EGR suction regulator.

One large line in the rear goes to the PVC valve.
