My 2003 CTS is leaking fuel near the rear passenger tire. It leaks when the vehicle is running, but stops when it is cut off. Can someone please explain to me what I can do to fix the issue? Kinda short on money due to the holiday season. Any quick fix recommendations until I can get it fully repaired?

 

On my 2006 CTS, that is where the fuel pump is. It's probably the fuel pump or the lines connected at the fuel pump. Thought I posted this reply yesterday but I don't see it, hope it doesn't duplicate.
