O-ring for fuel pressure regulator to fuel rail

[OneQuikSix]

Anyone know where I can buy a new o-ring for the connection between the fuel pressure regulator and fuel rail. I tried some injector o-rings from AutoZone but they are not large enough. Advance Auto didn't have any either. I tried a search of this forum but could only find info related to fittings and upgraded fuel lines. Any direction would be greatly appreciated.

BTW, it's the same as the 12 that seal the fuel injectors to the rail and intake. So if you have some of those laying around...

I went to ACE hardware and they had a toolbox filled with assorted o-rings. I brought in my old dried out ones and found an exact match. Strikeeagle is right, they're the same as the orings on the injectors.

Thanks for the help. I guess the ones from AutoZone are slightly smaller than the factory ones. Thanks again.

Carquest had them in here.

I was successful last night at a local O'reily Auto Parts. Even though the outside diameter of the new o-ring looks slightly smaller, it fit snugly into the fuel rail. I guess the original one was somewhat distorted. Anyway, no leaks.
