Throttle Body fuel leak?

This is my mother's well-kept from brand new car. I am a few hundred miles from it and relying on her neighbor for info. I'm hoping to use the info obtained here to travel there and make the repair in one trip! The neighbor says that it is leaking/ seep fuel from a fuel line that enters the throttle body. I have no idea if this is a pressure line or a return? Is it possible that you can show me multiple pics of the fuel lines in that vicinity, what they are made of, and any helpful installation tips? Thank you, CJ MEDEVAC
