About Fuel Injector O-Ring

Fuel injector O-rings are rubber rings in a car's fuel injectors and they supply vacuum pressure for the injectors.

Fuel injector O-rings operation

The fuel injector O-rings are responsible for supplying vacuum pressure for the injectors to operate correctly so that no exterior air leaks gain access to the injectors. The main function of the O-ring is to seal all fuel and fuel vapor from leaking into the engine section. Typically the rings are made of a type of rubber that is petroleum and resistant to hydrocarbon. That is why it is important to have a productive O-ring to keep the vehicle from leaking oil.

Common issues with a faulty fuel injector O-ring

A faulty fuel injector O-ring can lead to engine misfires, poor fuel efficiency, and a decline in engine performance.
