Default Intake manifold vacuum line
There is a small (1 inch) vacuum line at the rear of the intake manifold. It appears to supply vacuum to the various valves/solenoids that sit on top.
Anyone ever replaced it? The diameter seems larger than the rest of the vacuum lines.

AHA 30v. You can see the "T" connector here. The bottom of the T is a much larger line than all of the other vacuum hoses.

Yes or No: Does the vac line at the FPR go to 1 of the 2 small nipples under the intake manifold?
