thanks for the reply. I thought there might be a "this is usually what breaks" type answer. I guess I will have to break out the diagrams and 'git' to work.
One thing though: the lines next to the battery are all rubber hoses. It seems someone changed them before me.
P.s. Am I on the right track with the vaccum system or did I miss someting obvious (a.k.a. make a stupid assumption) ???
