Bottom of air guide. Only accessible with intake loose or off.

So, unless I can see an unconnected and otherwise unidentified vacuum line peeking out somewhere, I need to delve under the intake to ensure this air pump vacuum line is capped off.....

- And does anyone have a good diagram or set of pictures of the vacuum lines setup for a 1990 GT?
- I do not have the decal in my engine compartment, and my online searches have produced some conflicting schematics.

Does the vacuum line from the air pump go directly under the intake or via the multi-port vacuum manifold at the rear of the engine (the one connected to the fuel pump regulator and dampers)?

Ok, apparently it goes directly under towards the back of the intake.

Thank you. This would be a new and major project for me, so I need to plan this out.
