GM O-rings for cross over pipe
I don't know the sizes, but for a C6 here is GM's part number for the their package of the two o-rings found inside the neck of their Tank Asm-Fuel . Each tank takes one package which includes one black and one yellow o-ring. That part # is 1037-6929. Mechanics have confirmed they slightly lube these with grease (something like dielectric grease) when hooking up the cross over pipe.

Recently changed the stock pump in my 2011 GS to a Z06 pump. A couple of the o-rings got buggered trying to get the cross over pipe unattached. I just took the old o-rings to a hardware store that has a good selection of metric and SAE o-rings and matched the size and diameter. I used Viton.
Also used Sil-glide to lube up all the o-rings and connection parts. Everything went back together with almost no effort and my fuel system has been working perfectly.
