Fuel Line Assembly

What is your question?

On my Saturn 1997 wagon SW2, it is leaking gas from the return fuel line in the engine area. I was told that this line (the part) is not available individually, and that I would have to replace the entire fuel line assembly all the fuel lines and am being told it is a special order from GM because the car is so old and that it would cost $570. I just want to make sure that this is true. Thanks to anyone who can help me.
