The EGR vacuum line circuit begins with a rubber line (ca. 6cm long) that goes from the top of the valve itself to an intermediate steel tube held from the back of the motor. From the other end of this tube, via another rubber line (ca. 5cm long) it attaches to the tube under the plenum in your picture. From there to the solenoid actuated vacuum exposed valve that is mounted to the shock tower, You can bypass those and go directly to the valve. I do have those pieces and will not be using them as I am dleteing the EGR system. You are welcome to them for postage.
