i just checked my 72 that has a canister, one line tees into the pcv, one line to the tank and the third is hooked to a nipple on the side of the carb under the choke pull off. i'm assuming it's correct routing as it passed calif emissions last time we had to smog it and i have not changed anything since then. your canister is different than mine in appearance, mine has three different size hoses and the one hooked to the side of the carb is pretty small. i hope this helps but it probably makes it more confusing.
