2002 grand am gt v6 3.4l, I disconnected the fuel feed line that goes into the fuel rail and need to replace the o-ring before putting it back. The original o-ring was brown, maybe 3/8" inner diameter, and was thicker than other fuel line o-rings I've seen. Does anyone know what part number it is or where to get it?

I found a similar fuel feed line looks like it has the same fitting (part #12569127) but it doesn't seem to be available anywhere:
