BTW- My Grand Prix is a 97 w/ a 3.1L

I did go to the dealership and they brought up the fuel lines, but all it showed was the fuel line. It didn't appear as though there was a more exploded view of the fuel line showing the fitting, o-ring, etc.

However, when he looked at the part number, it showed all the related parts and he came up 17077609 and 22514722, both o-ring seals. The 1707 looked like it would fit, but I bought both and ended up installing the 1707 part. The 225 looks like the o-ring that goes on the end of the fuel filter.

It seems to fit well, but I haven't got everything else bolted together so I can prime the system and check for leaks.

Thanks for your help. I'd still like to see what you come up with.
