Product Details and Specifications

Installation Notes and Tips

When installing the Four Seasons Filter Drier 33401, ensure the flare fittings match the 0.500 inch diameter inlet and outlet connections on your Mercedes-Benz 300D. Use the included green O-rings and gaskets to achieve a proper seal and prevent leaks. Since the mounting bracket and washer are not included, verify that your existing hardware is compatible or obtain replacements as needed. Avoid reusing old desiccant filters, as they cannot be replaced separately and may compromise system performance.
