Mercedes 300sd fuel line leak how to shut off?

Question

ok i unpluged one of the rubber fuel return line, because it's squirting out fuel, and found a crack in the line, so i reattach it (so i can go and buy a new line) but it's leaking out of control, it won't stop, i'm wasting expensive diesel, how can i stop the leak, fuel shut off switch?

help!

i don't know what i'm doing, this is my first diesel

Answer 1

That's the diesel return line that jumps between the cylinders and no, once it starts leaking, the only thing you can do is to replace the line.  Just borrow another car or get someone to drive you to a Benz dealer to pick up that line ( the good news is that it's not very expensive ).
