I have a 1997 turbocharged LS motor; there is only one vacuum source on the intake manifold. If I T that off to 4 more ports using standard Ts, does that decrease the strength of the vacuum pull?

I need that vacuum source to tap into: a 3-bar GM map sensor, fuel pressure reg, and wastegate. I just want to make sure it will get the right amount of vacuum pull even though it is only coming from one source.

 

and what vacuum source is that? what about the break booster. lots of people take vacuum of that and t it into 4

 

It is the original vacuum source for the fuel pressure regulator. But does Ting it off into 4 decrease vacuum strength?

 

I tapped 4 ways. Its fine especially if you are tapping sensors which don't put any real drain on the vacuum since its all a closed system!

Thanks for the info...
