The EGR solenoid is located in a plastic covered enclosure on the passenger side firewall. It takes vacuum from the manifold on hose no 16 then goes to a constant air regulator, solenoid then connects to the EGR valve on the intake engine near the top hose to the radiator. For the hose that goes down toward the rear motor mount, where does the other end go. Are you sure it is on the vacuum circuit or is it on the fuel circuit? Can you take a picture of the solenoid?
