Nope neither one of them is correct, just like in Richard's picture the 250B linhai intake manifold has two vacuum ports.  |

It's not too hard to make a splitter plug, or drill a hole and plug in the plug with some silicone.

Two things, the emmission stuff causes no performance issues as long as it's all properly hooked up and second even though you can put a Tee in and use one vacuum port it's better to use a "Y" connector.
The linhai does better if you isolate one port to the fuel pump only and run the second port for the other items. Not hard to add a second port even on a new single ported intake.

Here is the pic of where the vacuum lines are now  The one closest to carb goes to fuel pump and carb, back one goes to canister and emission stuff. Attachments:
