<1991 350SD> I was trying to remove my washer reservoir yesterday and the hoses to the pumps would not come off so I cut them. That's when I discovered that there some WIRES running inside one of them that lead to a ?temp sensor?. Should I worry about that? Looks like $$$$ to replace that hose. AN-y-how, the reason for the investigation was that all my fluid was leaking out. It turned out that one of the rubber gaskets around the (same) pump stem was shot and leaking. Easy fix on that. But now ???????
