2004 Buick Rendezvous - Gas leak

Gas line leak just behind the engine near the transmission. So much gas leaking I can’t tell where the exact location of the leak is. Do I need to have the entire gas line replaced?
It’s certainly not safe to drive.

You said have the whole thing replaced . If you having a shop fix this then go by what they say . No one on the web can see what kind of shape the rest of the line is like .
