The can is not original & I don't think there ever was a diagram published by Packard.

The distributor tube is a small steel line and comes off front of carb base straight across engine and drops down to a clip in the plug wire holder and then to dist vac advance unit.

Believe on yours the wiper vacuum supply starts at front of intake manifold & drops down to top of pump exhaust side. Thru pump & out inlet side. From pump via a steel tube along side of engine block in that space just above pan to rear where it bends up a few inches at the firewall and changes to a rubber hose. If there is a vacuum antenna or other small vacuum options believe there will be a tee in that short length of hose just before wiper motor to supply the options. Vacuum antenna would get it's supply from the tee via a rubber hose to the grommet near side of cowl and in to valve. Hoses from valve to antenna out the grommet and then drop under fender to antenna

If you have the Electromatic clutch, that supply is a large steel tube from clutch control valve, straight across engine where it drops down and goes into a large fitting in manifold just below carb. The power unit tube is steel from control valve, goes forward along drivers side of engine where it turns 90 degrees and down to a short hose connecting to power unit.

All factory tubing is steel -- although some pumps had solid steel & fittings connections for the vacuum and others had short rubber hoses between the pump and steel lines.
