Im trying to install a Mechanicall boost gauge on my 06 cobalt ss/sc what is the easiest way to get the Vacuum hose through to the engine, also where do I need to insert the tee or i should ask what hose do i run it off of if someone could just give me a quick run through that would be great im so lost lol my electric gauge went out on me the light comes on but the needle dont move. Thanks in advance.

 

Tie your vacuum line to a coat hanger and push/pull it through the hole in your firewall where the split grommet is below your pedals. You can tee from any vacuum line off your intake manifold. I wouldn't use the ones for the bypass solenoid tho

Or just buy my stock boost gauge i have lying around lol
