I have the TB and UIM off because i was having some issues with my hot start and i am upgrading my injectors. My question is what vaccum lines do i need to keep? the previous owner only has two hooked up on the firewall side of the TB and the rest open, am i missing any to actually run things and should i cap off the other ones?

 

Bottom and top of firewall side of tb are injector air bleeds, thats all you need! Bottom of bumper side is the only vacuum/boost port on the TB, thats for the omp....
