I have a complete set of the (6) injection lines from the distribution blocks to the injectors. This will fit all W111 220SE motors. They were previously rusted and have been cleaned and zinc plated. Only the outer exposed areas are rusty, not the sealing cones which are in good shape. There is visible pitting from the rust but has been neutralized and then zinc plated.
The insides were flushed out and cleaned with an abrasive wire to remove any internal rust or scale. All lines flow very well. While not pristine, they will work well and are protected from further corrosion. Free with shipping in the US.
