fuel leak

Hi,
I have a fuel leak here






I am not sure whether it's the hose or not (which isnt pictured), but do you guys have any idea where it could be coming from? Oh and I grabbed that pic from rotaryresurrection so this isnt the car.

The car is a S4 TII with a S5 engine & manifolds
Thanks

That's like the second time Ive seen this picture for the same problem...

That's the pulsation damper. If its leaking, it's very bad. You should replace it with an aluminum one from Marren Injectors. It's cheaper than buying a factory one from Mazdatrix and it will definitely last longer.

Oops, just saw that...lol.

Sorry, mate.

I believe that part you circled is the pressure regulator.

It is the fuel pressure regulatory, but I dont think fuel comes out of there unless it's broken malfunctioning somehow.
