For my "driving setup", I remove the short hose from the end of the steel line to the distributor and close off the end of the line with a rubber cap, and add a longer rubber hose from the vacuum advance can to the existing white plastic tee in the choke pull-off hose. That tee normally has the rubber vacuum signal hose to the diverter valve connected to it, and I just disconnect the signal hose from the tee and let the hose hang (doesn't matter, as I have a BB in that hose anyway and the A.I.R. pump is gutted).
For "correct appearance", I just remove the long rubber hose, remove the rubber cap from the end of the steel line, re-install the original short hose from the end of the steel line to the vacuum advance can, and re-connect the diverter valve signal hose to the tee in the choke pull-off hose.
The steel clip for the steel line is there, but it's hidden behind the brass fuel line Y-block in the photos.
