How to diagnose and replace the fuel pump in an Audi 80?

I suspect I have a faulty fuel pump in my Audi 80 and I want to know how to diagnose and replace it myself. Can anyone provide step-by-step instructions or guide me to a reliable resource? Thanks!

First, you'll need to locate the fuel pump in your Audi 80. It is typically located inside the fuel tank, so you'll need to remove the tank to access it. Then, use a fuel pressure gauge to test the fuel pump's pressure. If it is below the recommended levels, it is likely faulty and needs to be replaced. For more detailed instructions, check the Audi 80 owner's manual or a trusted repair guide.

Before attempting to replace the fuel pump, make sure to disconnect the negative battery cable and relieve the fuel pressure. To replace the fuel pump, you'll need to remove the fuel tank and the old fuel pump. Make sure to clean the area before installing the new fuel pump. Once installed, connect the fuel lines and reattach the fuel tank. Don't forget to reconnect the battery and test the new fuel pump before starting your Audi 80.
