vacuum line ? v8

[2002yanks]

need help finding out where a vacuum line goes. motor is a 302 from a 99 mountaineer. ok the line goes from the fuel vapor management valve(under the battery) to the underside of the manifold(front). now off of that there is a line built in for vacuum but it wasn`t hooked up. i searched all over for a hookup point, but couldn`t find one. anyone know where it goes?
from here fuel vapor management valve

to here

lose line here

also would this have anything to do with the code i am getting(p1451)?i replaced the valve you see above, the charcol canisters/ solinoid on them and the hoses connecting them. i am getting 12 volts to the canister.
