My fuel pump lines do not have the side clips (2004 A4 1.8 Quattro). How do I remove them?

 

Before you go thinking about someone trying to cut your fuel line, that looks exactly like a rodent chewing on your car. Yes, the line AND the body. To answer your question about fire? Yeah, it's a real concern, fuel leaks often cause big fireballs in cars. You say you know how to replace a fuel line, you should throw down some bait traps around where you park. Does the car get parked in a garage at night?
