glx 2002 passat v-6 30 valve wagon / 4 motion / automatic. installed new vac. lines or most of them coming off the plate. How ever there is one small tiny tiny plastic line running off bank one side and under the plate across to bank two area. There are actually two lines like that but one runs up bank one side along cylinder head to the front that is connected. But this one little plastic line just seems to run no where. so I just taped it off. what could it be. where might it go nobody knows.
