what size hose did you use? how did you keep the hoses from kinking? The is a built in 90 deg. elbow at the wastegate and intake manifold. How do you remove the metal clamp at the intake manifold, BPV and wastegate? What is the size of the nipples at those locations (I guess that would dictate what diameter hose to use?). I decided to replace all the stock vacuum hose becuause I don't like them!! They are too stiff and brittle. Any reason why I should not do this? Thanks.
