Vacuum Line Question. D32E-AA

Hey guys, I've got a 79 F250 with the 400. I've been searching the web for hours and I just can't find out where this vacuum line goes. It's part number D35E-AA, the little black and white one, coming from the Vapor Canister Purge Valve, or the Purge CV as it's listed on the crappy line diagrams that I find.

Anyway, it came off and I have no idea where it's supposed to go. It's hooked up on the Purge CV end, but not on the other end. Any idea where it goes? Anybody got a picture for reference? I've read a couple threads that said it hooks up on the back of the carb, but I can't find out where. Thanks for any help. I sure wish there was a better vacuum diagram for these trucks...

It's ID Engineering number prefix/suffix: D32E-AA, the little black and white one, coming from the Vapor Canister Purge Valve, or the Purge CV as it's listed on the crappy line diagrams that I find.
Evaporative Emission (Evap/Em) system: Unleaded fuel, non vented fuel cap(s), vapor valve in the fuel tank(s).

Evap/Em vapor lines route from the vapor valve(s) along the inside of the right frame rail to a charcoal canister located under the hood. 1978/79 canisters are plastic and rectangular.

A hose routes from the valve on the canister to a plastic elbow on the air cleaner.
