GASKET - O-RING FUEL FILTER (Toyota TY00591-16573-81)

A damaged fuel filter gasket can allow unfiltered fuel to bypass the filter element, leading to injector or pump contamination. This aftermarket replacement part references the Toyota catalog number TY00591-16573-81. The gasket is an O-ring type that seals the fuel filter housing to prevent leaks. A failed O-ring may cause fuel seepage, resulting in low fuel pressure or air entry into the fuel system. During a filter change, the old O-ring should be replaced to maintain a proper seal.
