to be totally honest, the only small vacuum line you have to run is one to the FPR. All the rest are emission related.
And the black canister is also connected to the fuel tank breather line, unhooking this and leaving it vented to the atmosphere supposedly looses alittle more gas to evaporation(the vapors would normally collect in the intake plumbing when it's all hooked up, and get burnt up at startup), but that may just be a rumor.
