Charcoal Canister Help
Best thing to do is refer to the shop manual. We recently had a 73 shop manual show up for download, end of this thread:

Read the fuel section, and section 25. See page 25-26.
Vent line to tank
Vent line to carb fuel bowl
Canister purge line (vacuum)
If you decide to strip it out the main thing you need to watch is that the line to the tank must remain, in some form, as a vent, or you must construct a vent in some form.
