84 GL, was cleaning around the oil pump and the oil pressure sender wire (copper eye) that was hanging on by a thread broke off.  The screw with the rubber washers above and wire connector below doesn't loosen or tighten, and that seems like the place oil is dripping from. Is that screw sppossed to do that? do I need to take off the whole sender unit?  if so, how do you get a grip on it. haynes isn't telling me much on this. thanks.

quick fix?

that screw is just the electrical connection if there is oil leaking from there replace the sender.

I was hoping to take the screw out to replace the electrical connection, but it just spins. not sure how to get a grip on the sender unit, is there a special tool? Its not finger tight.

its the ground wire, and subaru said they strip easily.
