I have a 2007 Hyundai sonata with a 3.3L v6 I need to replace the O ring that goes on the fuel line that connects to the fuel rail . I'm having trouble finding the size of the oring.
measure the OD (outer diameter) with a caliper and buy the correct size.
Make sure to use Viton or other chemical resistant rubber for fuel lines.
Alternatively, you could just ask the part store to supply the part using your vehicle info.
What is it exactly called? For me to ask them. Sorry, I'm just new to this. The fuel line is metal. On the end of the metal has a oring. That metal fits inside of a whole on the fuel rail and has 2 bolts that tighten it down.
probably just o-ring.
You're gonna have to show us a photo because I have no idea what you're looking at.
