Which vacuum lines do I need? what goes where?
so I recently purchased and installed a performance carburetor that I don't think uses a vacuum to operate, where my stock did. I also purchased and installed a performance uni filter and exhaust and after removing the stock air box and attached hoses, I'm not sure which need to be attached to the intake manifold (which has one vent on it) where do I start and how do I know which ones I need and which ones I can remove completely. I have a lance gsr gy6 150 if it makes a difference

Welcome to the site.
We need pics of your set up in order to help you out. Otherwise, let me try and help you... That one there, can stay. The one over here, has to go to the flux capacitor. Otherwise your warp drive will never engage.

The one from the intake feeds the fuel petcock and the CVT bleeder.

Not sure what your setup is or type of carb you have . If you have the vacuum fuel pump(2 hoses go to it under fuel tank) one vacuum hose will go to it the other vacuum will go to the air bleed diaphragm on right side of carb if so equipped.
