Vacuum Hose Routing

I finally got the correct vapour cannister for my '72 318 , and am now wondering about its hose routing ...
Can anyone provide a vacuum hose routing diagramme , or at least a link to where I can ascertain that info ?
I checked Barry Washington's excellent Hamtramck Historical site , but have only found info for the 198/225 and 400/440 cars .

Thanks !
