I know this is an old post, but I tried this MAGNETI MARELLI 313011300066 pump recently. It has the small output in the bottom to pressurize the venturi system, but I never got it to work unless I topped up the fuel level high enough to fill the collector, lets say, naturally by fuel level.

Then, I went to start the S8 in the garage, and now it is completely dead. Its not seized (like the one that came out), but even when wired direct to the pump, it does not run. It is behaving like an open circuit.

Has anyone else fitted this Marelli Pump and had problems, either with normal fitting/operation or reliability?
