My car is a Quattro and so has a split tank with a pump in each, the second being a mechanical slave off the first, sending petrol from one tank to the other. They are both submerged in petrol in the tanks.
I had just the same noise symptom; the sound is hard to locate, seeming to come from all around. It turned out to be the fuel pumps. Mine is a quattro therefore has a split tank and the noise only completely went when both fuel pumps were replaced. The second one being mechanical slave to the first.
