Noisy Fuel Pump?
Hi I'm writing from Australia and have a 1993 Audi 80 - 2.3. I believe the vehicle was assembled late December 1992.
There is a noise from the rear - fuel tank area while the engine is running - can be described as a whirring sound but is a bit more. A Mercedes mechanic suggested there might be a fuel pump in the rear, at the tank, to maintain fuel pressure for the injection system (?) and that it would sound like that if it was worn.
I've not owned a vehicle with fuel injection before and as I cannot locate a workshop manual for my model (apparently Audi over here don't release them to the public - how pathetic is that?) have no idea where to start.
Can anyone please offer some real advice. If it is a fuel pump is that something a home mechanic can replace or is it a more specialised job suited to an Audi workshop?
Thanks (in anticipation) for any input.

It's very simple, remove the carpet in the boot. You will see a round plate, remove it and there is the access to the fuelpump. Very easy to remove and replace, no special tools needed and you don't need to remove the gasoline.
I believ Haynes has a manual for these cars, so I suppose you could get one online.
Im not sure if you already solved your problem, but you get into the fuel tank from the boot. Theres a port that goes into the fuel tank and the pump is in there as well. Good luck!

As long as the vehicle is running I wouldn't worry about it unless the noise is annoying.
Yes fuel pumps do make a little noise but you normally can not hear them while the engine is operating.
You can replace the fuel pump, you need some tools, some fuel cans, a hose, a friend, car jack, jack stands, and a 6 pack of brew.
You start off by putting the hose into the place where you put gas in from the gas station. **** on the hose gently until you get fuel flowing and put the gas into the gas cans. Once you get all or most of the gas out, drop the fuel tank down and thats the hard part.
You could take it to any shop to replace the fuel pump.
More than likely it is inside the tank...
