Fuel injector O rings are rubber gaskets around the end of the fuel injectors that hold the injectors up tight to the rest of the cylinders of your engine, and prevent fuel from leaking. If they’re not properly mounted, or if they’ve begun to deteriorate, you will lose fuel. They work like any other gasket – they will wear and crack as they age, and at some point will require replacement.
Fuel injector o-rings are not part of a maintenance inspection or service and are only addressed when there is a fuel injection problem or a fuel leak at the engine. If you suspect your fuel injector o-rings are leaking, have one of our expert mechanics inspect and replace them as necessary.
A fuel leak at the engine can cause a fire if the fuel ignites. Have leaking fuel injector o-rings replaced as soon as possible.
