92-95 4.3 vortec vacuum line placement--runs then hesitates at throttle up-

[offroadjoe1012]

I have a 94 4.3 vortec, I installed it in a different truck. All vacuum lines were removed so I am running blind hooking them up. There are 2 locations for vacuum lines-- one at front , under and slightly back from throttle flapper, I am guessing is from purge canister? And one on passenger rear of engine which has vacuum in it. I need to know the route it takes from the rear vacuum source in relation to the complete purge canister hook up, tranny control (i have non-comp th350) and "bubble" vacuum ball. My purge canister has 3 connections on it, 1 to tank, one large vac style hookup, and just above that ,1 small vac hook up i think is the vac trigger.
Hayes book says poor idle, stalling, poor driveability c an result because of improper vac line place ment, but they dont tell me what correct is! The truck will start, idle, sometimes its a little slow idle, but when i try to rev it, about half way through it cuts out and i hear a "sucking" noise until I release the throttle and it goes to idle again, fuel pump brand new in-line, just changed fuel filter. truck also will just quit unexpectantly and not start until its cooled 20+ min or so.-- Vapor lock due to messed up vac lines/purge maybe? I also thought maybe new filter clogging -tank sitting for several years with a little gas in it--i did add new gas and run it out pump before I connected it to engine. Any help would be appreciated--If anyone can e-mail or send vac hose placememnt picture or i-net link were one is for this 94 4.3 vortec --greatly appreciated! Thanks Joe

Front one is for the EVAP.

Back large one goes to the brake booster and the small one connects to the vacuum ball and the connections for the HVAC controls.
