MK6 Fiesta 2003 Hissing from Engine Bay. Fuel Return Line?

Hey guys I am new to the forums, I have a 2003 Mk6 Fiesta 1.25L 5 door in pepper red burgundy. I have noticed a hissing sound from the engine bay that I have narrowed down to (what I am assuming) is the fuel rail return line. It has a quick release clip with a red button on either side, this clip is situated on the right side of the fuel rail while facing the front of the car. I removed the clip and the hissing stopped, it would also change pitch if I wiggled it (fuel didn't go everywhere). I was wondering if anyone knew where I could get a new clip/internals of the clip. 

As well as the hissing, on start up I can smell petrol while outside the car. The smell goes away after a short amount of time  Could this be because of the hissing fuel return line? Because the cat hasn't heated up? The MOT is next month and I am worried that it could fail because of that. 

Thanks for your time, any help would be appreciated! :smile:
