* Fuel injector O-rings: These are individual O-rings that seal each fuel injector into the fuel rail. These are the most common gaskets to need replacing related to the fuel rail.
* Fuel rail gasket(s): Depending on the engine design, there might be a gasket or seal between the fuel rail and the intake manifold. This is less common to replace than the injector O-rings.
You'll need to specify the engine size to get the exact parts. A parts store like AutoZone, Advance Auto Parts, or Napa Auto Parts can help you find the correct gaskets based on your vehicle's VIN or engine code.
