Holley 2 barrel vac diagram

Does anybody have pics or drawings of where the vacuums lines run off a swapped holley 2 barrel 350cfm. I have most of the lines run but cant figure out a few of them, like the one that runs from the top of the fuel bowl at the pump plunger arm and the one off the side of the fuel bowl that almost looks like a spark advance. Any help would be greatly appreciated. BTW i am running an 81 200, c-4 auto, Dual outlet ceramic coated headers, smog and a/c removed, with DUI upgrade.
 
So i shouldn't attach any vacuum to the one coming off the fuel bowl? I've never done a 2 barrel swap and I don't want to jack anything up. I tried to do this awhile ago and I had problems with the motor running away when I started it up. Everybody said I had a vacuum leak but everything was where it should have been. But i did have a line on that nipple and am wandering if that was causing the accelerator pump to stick on and keep feeding fuel. I'll have to try it disconnected. Anybody able to verify anything? It would be very much appreciated. Thanks in advance.
