Hard to know if it is purple in the picture, but if it is, it runs down to the air pump valve (SAS) right behind the engine, sort of sticking up and looking like a brass mushroom. This is the vacuum to know temp of air from the airbox so it will know if it should turn on the initial air pump, if I'm correct. Good luck and please let me know where the line goes.
