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.

Replacing a fuel pump can be a tough job. you don't necessarily need to go to the Audi shop. In actual fact there may be an access hole above the fuel tank either in the trunk or under the back seat. it will be oval or round and have several bolts or screws holding it in place. you remove the access plate and the sending unit which holds the fuel sender and the in tank fuel pump will be right there. just a matter of either un screwing a large retaining nut or a few bolts or screws and it will come right out. If there is not an access hole the tank would need to come off and you might want to leave that to the guys at the garage. but that would be your call. you are the only one who knows your abilities are.

    the fuel sending unit and pump must be located through an access hole. I just looked up the times and the fuel pump replace time is 1.4. and the fuel tank replace time is is 3.9. so the tank does not need to come out to replace the pump. mike

The bearings in side the pump are shot , you should replace this unit before it goes . usually not long after it starts making noise. hope this could help you .

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!

Where is fuel pump relay in audi 80 ?


Hi there...if your audi is a B4 same as mine....fuse and relay box is located under the engine hood, driver side ....if you are italian....or passenger side side ..if you from Uk....just lift the hood, and check below the windshield in the gutter ...you'll see a black plastic box...here you go!
lift the lid...look for a grey box with the # 209 (if I recall correct..) ...that is your fuel pump relay...easy to replace.

hope this can help and regards

Noisy Fuel Pump?


Greetings from America!!

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.

Injcetion unit control


What your describing sounds like a bad fuel pump or vapor lock. If any of your fuel hoses are running near the exhaust move them or rap them. Is your fuel pump really loud?
