Your car has a fuel return system which means unused gas goes back to the tank. With MY02s the cars went to a sealed non-return system.

As Randall said, the sending unit and also the pump is in the fuel tank. Could be the sender, but I'd check/replace the (external) fuel filter and inspect the lines for kinks first. A clogged filter will impede fuel distribution. The external pressure regulator could also be a problem.

While it does sound like a vent symptom, I don't know if that is likely in a recirculating system.

Anyone?
