How to replace the fuel pump on an Audi 80?

I need to replace the fuel pump on my Audi 80, but I'm not sure where to start. Can someone provide step-by-step instructions on how to do this?

First, disconnect the negative battery cable to avoid any potential electric shock. Then, locate the fuel pump, which is typically located under the back seat or in the trunk. Remove the old pump and install the new one, making sure to follow the manufacturer's instructions.

Before replacing the fuel pump, make sure to relieve the fuel pressure by disconnecting the fuel pump fuse or relay and running the engine until it stalls. This will prevent any fuel from spraying out when you disconnect the fuel lines.

It's always a good idea to wear protective goggles and gloves when working with fuel, as it can be flammable and corrosive. Also, make sure to clean the fuel tank before installing the new pump to ensure it works properly.
