Default 99sc300 intake manifold vacuum??

Did a tune up on the daily and found out something is missing...

Does anyone know where this nipple or what vacuum line goes on here?


I tried searching and didn't find anything. I also have a dealers manual and that did not say much or anything about what goes on that area.

If I remember correctly, mine has a black rubber plug over that nipple.

that one is for the fuel pressure regulator, some motors will have a VSV in between that nipple and the regulator and some go directly from the nipple to the regulator

there should be a vacuum routing diagram on the underside of the hood

Just cap it off , on my GS300 it has the same and it's capped off.

They made that penum for the ge non VVTi and the VVTi so on the non VVTi , it's a Valve that hooks over there
