Ok so the kit is all set up no oil leaks as of yet however I'm wondering right now about all my vac lines.

I have one line running from the nipple on the top of the turbine housing to the bottom port of the wastegate. (turbosmart ultra-gate38)

The top port on the wastegate I left open

the nipple on the top of the blow off valve I ran to the bottom vac line underneath the fuel rail.

So this leaves the top vac line under the fuel rail open can I just cap that off not really positive what it goes to and/or if it can just be capped off. Quick responses appreciated I'm supposed to get it tuned today at 5

 

Oh I put a T in between the wastegate and the turbine housing for a boost gauge as well, figured i might as well mention that
