I have a Japanese spec 92 with 25 K on the clock. All the vacuum hoses are hard as hell so I've decided to go simplified. Just a couple of small problems though. Looking at Mike Putnams vacuum hose drawing, I presume the brown, yellow and green lines go through the lower manifold and are not connected to the inlet tract or each other, is this correct? My car has no fourth nipple that Mike shows in yellow going to the pressure tank, so I connected the stray yellow from the turbo Y-piece, on the assumption that I would get pressure to the tank from there. I also have a second nipple on the primary turbo intake elbow that the drawing seems to show as part of the casting, and going to the discharge side of the turbo, any suggestions on what to do with that. Finally which type of the check valves should I use.

Peter.
