What is the Fuel Injector O Rings?
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 stop fuel from leaking. If they’re not correctly fixed, 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.
Facts to Note:
Fuel injector O rings are not examined as part of your routine upkeep, but if your car has accumulated tens of thousands of miles, it is a good idea to have your mechanic check them out.
If your car is losing fuel, the rings may be at fault.
Don’t assume that the problem is with the O rings – your injectors could be clogged.
How to Fix:
The vehicles hood is opened and battery disconnected
The faulty fuel injector O-rings are removed
The new injector O-rings are fixed
The battery is reconnected and engine started
The repair is confirmed for no fuel leaks and tested for proper operation
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 your expert mechanics examine and change them as necessary.
Common signs indicate you may need to change the Fuel Injector O Rings:
Fuel leaking at the engine
Car not starting correctly or running rough
Importance of this service:
A fuel leak at the engine can cause a fire if the fuel ignites. Have leaking fuel injector o-rings changed as soon as yo can.
