what is best way to pressurize vac lines?

I am continuing to search for the cause of high NOX levels from my 83 944. This forum seems to contain several responces from similar questions that point to a lean condition caused by vac leak.
I have pretty much double checked everything visually. I have seen a couple of posts that suggest pressurizing the system to 15 psig but i couldnt find any suggestions as to where the pressure should be applied. Does anyone know if there is one vac line better than an other to connect ot the compressor?

thanks

Well,....first off you will have a difficult time pressurizing the intake to 15psi......

The best way to visually find a leak is with a smoke machine...

Well, a turbocharger would help

Sorry, had to. . .
