I am turboing my 1990 Volvo 240 and was wondering what you do with the vacuum lines connected to the intake manifold. I already know that you reroute the main flame trap hose to the intake on the passenger side but what do I do with all of the smaller ones?

Thanks

Need one for your blow off valve. Hvac control, should be one going to your FPR. You should probably install a one way check valve on the hvac so you're not blowing pressure into it. Same with charcoal canister lines if you're keeping them.
 
The bypass is mounted on the turbo, and yes you need to hook it up. It has nothing to do with the wastegate.
And you should just leave the charcoal canister alone.
You obviously haven't completed your research on a +T. Not trying to be mean, but you need to dig deeper and come back in a few days. You are showing a lack of understanding how a turbo system works.

That’s why I’m asking here
 
Right so I know what a bypass valve does but wont all the vacuum lines will be pressurized because the intake manifold will be pressurized, so I’m wondering what vacuum line I should be hooking it up to.
