I have no idea how the electric fuel pump works...but, if it is like the manual fuel pump here is how I fixed the problem;
The manual pump, does not suck fuel, it pushes fuel into the carb. If there is air in the fuel line, the manual pump will not push the fuel.
Disconnect the fuel line between the pump, and the carb. Clear the fuel line of air between the tank, and the filter with a hand pump bulb. connect the pump to the carb, and start your A4.
MM should know if the electric pump is a sucker, or pusher.

Up date The manual fuel pump does suck from the tank, and push to the carb. I have cleard all fuel from the tank to the pump. Have cleared all fuel in the pump. Hit the starter, and within seconds the engine is running. Air in the line does not stop the manual pump from sucking fuel from the tank. The fuel line from the tank to the pump is over six feet. If the electric pump has the same sucking power, you should have fuel in the carb.
