I need help locating a part that pertains to the Emission Control System for my 1980 Mercedes, 450SL. The part that I need is the "Air Intake Line" - the line is metal and connects to the Air Inject Check Valve which attaches to a rubber hose that connects to the Shut Off Valve that connects to another rubber hose that connects to the Air Filter (metal) cover. The other end of the Air Intake Line connects to the motor (cylinder) of the car.

Help, help.
