Installation Notes and Tips

When installing the Four Seasons Hose Assembly 55543, ensure all O-rings and seals are properly seated to prevent leaks. The male and female springlock fittings require a secure connection; verify that fittings snap into place firmly. Although the assembly includes gaskets and O-rings, fittings are not included and must be sourced separately if needed. The hose assembly does not come with a bracket or muffler, so existing mounting hardware should be reused or replaced as necessary.
