Looks pretty good, as for the vacume line, i would honestly go with silicone instead on the stainless. I know it looks a lot cooler but you will need to remove your valve cover and thread the nipple for the fitting to work if you can get it to not hit the fuel rail. If you do this you can get an elbow and splice it in line. Silicone will work just fine as well and will hold far more boost pressure than the SC can produce. Very creative idea as well as resourceful.;Dr;
