Quick Boost Gauge Question

[kevdog240]

i just ran my vacuum line into the engine bay and was looking on the intake manifold for a vacuum line. im kinda confused which are vacuum lines and which are not since i have never played with vacuum lines. which one should i use? i was thinking of teeing off towards the back where there is a line going through some little white circle. in the chilton manual it looks like it says its a one way valve or something like that. anyways is that ok to use for the boost? which line can i use....

yes i do know that any vacuum line will work but the problem is i dont know which lines are vacuum lines.
