What are common issues with the Audi 80's fuel system?

I've been having some issues with my Audi 80's fuel system and I'm not sure what the problem is. Sometimes it fails to start or the engine dies while driving. What could be causing these problems?

One common issue with the Audi 80's fuel system is a clogged fuel filter. This can lead to decreased engine performance and difficulty starting the car. It's recommended to replace the fuel filter every 30,000 miles or sooner if you're experiencing issues.

Another possible cause could be a faulty fuel pump. If the fuel pump is not working properly, fuel may not be reaching the engine, causing it to stall or not start at all. This is a more serious issue and should be addressed by a mechanic.

It's also important to check the fuel injectors as they can become dirty or clogged over time. This can affect the fuel mixture and lead to engine problems. Regularly cleaning or replacing the fuel injectors can help prevent these issues.
