I found the blue/brown vacuum line and the fuel shutoff valve, which is below the other gizmo that i thought it was. In front of the oil FILTER, not cooler housing. When i applied vacuum, it smartly shut off at about 5 or 6 on the vacuum pump gauge. There is only about 3 coming off that blue brown tube, when i turn the key off. So i will follow the other excellent suggestions here to track down where that vacuum is getting lost, and report back later.
