GASKET - O-RING FUEL FILTER (JCB JC490786)

JC490786: A damaged fuel filter gasket can allow unfiltered air or debris into the fuel system, leading to hard starting or erratic operation. This aftermarket replacement part references JCB catalog number JC490786. The gasket creates a seal between the fuel filter and its mounting surface, preventing fuel leaks and maintaining system pressure. Over time, the rubber material can harden or crack, resulting in fuel seepage that attracts dirt or causes a noticeable fuel odor. During a routine filter change, the old gasket should be replaced to ensure a proper seal. The item ships at approximately 0.023 pounds.
