Vaccum leak codes

Did a smoke test and found smoke leaking from a place that's meant to have a vacumm hose I assume as loads of smoke bellowing out but don't seem to see a hose to put on it. Any ideas conversion to a 325 so wonder was pipe not put attached of pipe it's at back of engine under where micro filter is behind where intake boot.

There's a vacuum cap that goes there. There's also 2 smaller ports back there. If there's a valve on the back of the intake next to it then it should hook up to the smaller port if not just cap them off

You are missing a cap. Secondary air issues are discussed here. If these vacuum lines are original, replace them:
