The Audi 80 was available as a saloon and a station wagon. During the development of 80, many popular parts, such as the fuel pump, have been built. A fuel pump generally comes accompanied by a fuel filter. It helps eliminate any pollutants that can be stuck in the fuel lines, fuel tank, or pump itself. The mechanical fuel pump has a lever on the pump that actuates by riding on the eccentric lobe on the camshaft while the electric fuel pump is mostly run off an ECU or PCM which helps regulate when the pump shuts off and when it comes on.
80 has a lot of parts, while problems arise after the fuel pump parts have been used for a long period. You should remove the electrical connector from the sending unit carefully so you can avoid damaging or breaking any connectors. You need to make sure when replacing the fuel pump the regulator is working properly so you avoid rough idling or loss of performance due to high/low fuel pressure readings.
