How to troubleshoot a fuel pump failure in an Audi 80?

I recently experienced my Audi 80 suddenly stalling on the road and was told it might be due to a fuel pump failure. How can I determine if this is indeed the problem and what steps should I take to fix it?

The first step is to check the fuel pump relay and fuse to ensure they are functioning properly. If those are not the issue, you can test the fuel pressure using a fuel pressure gauge. If the pressure is below the recommended level, it could indicate a failing fuel pump. It is recommended to have a professional mechanic replace the fuel pump if needed.

Another possibility is a clogged fuel filter, which can also cause the symptoms you described. It is recommended to replace the fuel filter every 30,000 miles to prevent potential issues. You can also try cleaning the fuel delivery system with a fuel system cleaner.

If you are more experienced with car repairs and have the proper tools, you can also try removing and cleaning the fuel pump itself before determining if it needs to be replaced. However, ensure you have a detailed diagram of the fuel pump system before attempting this task.
