Please move this if it is in the wrong section, but I've got a question regarding vacuum hoses. I've already gone single turbo with a T04S and while I was in the engine bay I was thinking about changing out all the Silicon hoses too, but the it me. I don't really need all those vacuum hoses. So can anyone give me a diagram or tell me what vacuum hoses I actually need?

On a side note, What filter will fit on a .84 trim T04S turbo? I just want to stick one on.

 

you should be able to just measure the turbo inlet. prob 3 or 4 inch.

are you running any emissions equipment?
if not you really dont need much of anything. One line for the FPR, an atomization line for the injectors, if you want to keep the hot start solenoid you will need to check the routing for that. You can run a line for the oil injectors or just leave them open, the amount of unfiltered air that can enter is very minor. you will need a line for the oil vent.... screw it heres a pic.
