Default What are these hoses for?

Hey guys, just a quick question about exactly what the rubber hoses hooked up to the carb in this pic are...I'm fairly sure but I wanted to check as I'm installing my new Street Avenger 670 and just want to make sure the right vacuum hoses go to the right places...I'm talking about the two black rubber hoses in about the middle of the first pic and the one closer to the bottom in the second pic...

From memory: 1st goes to pcv, then to carbon cannister, second goes to carbon as well(?), back I think is for your headlights, other side for the wiper door (or visa versa)

I don;t have your 68 schematics goin off memory on my 79 which had no wiper door. Check shop manual or someone may chime in

Timbo is right on, the ones on the drivers side go down to the evap canister. Do your self a favor and check these hoses down at the evap canister. You need to pull the splash shield off to get a good look. I didn't know mine were cracked, On a trip to Vettes on the Rockies with a full tank, fuel was pushed up the return line to where the crack was so much fuel came out if I had side pipes we would have been toast. There is alot of heat near that canister which cooks the poop out of those hoses.
