2026 Update: This hose is getting harder to obtain. We do have a kit so you can make your own. See related products below: This hose assembly was used on the fuel delivery systems in the late 1970s and early 1980s. Installed on some R107 450SL and 450SLC, W116 450SE / L and 280SE, and the W123 280E and 280CE. Be sure to check your car before ordering to make certain this hose is installed.
