Basically, an O – ring is a simple circular gasket. It creates a seal between two surfaces, preventing fluids or gases from leaking out. They’re made of different materials – usually some kind of rubber or synthetic rubber – depending on what they’re sealing and the temperatures involved. You’ll find them all over the place, honestly. In the fuel system, like where this one fits, they seal fuel lines, fuel injectors, fuel rails, the fuel filter housing… pretty much anywhere fuel needs to stay contained. They’re also used in coolant systems, oil systems, brake systems, power steering… you get the idea. This particular one, being in the fuel supply, keeps gasoline from leaking where it shouldn’t. A failing O – ring, especially one in the fuel system, can cause all sorts of trouble. You'll notice if you start smelling fuel, see a fuel leak, or experience a drop in fuel efficiency. A leak can obviously be a fire hazard, and even a small leak can mess with engine performance. They act like a shield, keeping everything contained and working as it should. It’s a small part, but a crucial one. If you need a replacement, Fixparts Online usually has a good selection, and getting the right one is really key—they come in different sizes and materials for different applications. Worry-free performance: O-Ring (MPN WHT005422B) is covered for 12 months!
