I have an 83 300d. I removed the panel below the steering wheel and found a vacuum line simply resting against the back of my brake pedal. I raced the line and it runs through the firewall into the engine compartment. It is connected to the "T" that is on the bottom of the transmission modulator on the rear of the fuel pump. The other side of the "T" runs to the lower right side of the 5 way connector located on the valve cover. That is if it is viewed from the front. Does anyone know where this vacuum line is supposed to go. I looked under the dash and cant see anywhere it should be connected. Thanks for any help.
