Fuel pressure regulators?

Do these components go bad? Mine seems to work just fine but is OEM and is 12 years old. Does anyone know if these have a rubber diaphragm in them or any other parts that break down over time or are they all mechanical? (eg. metal body, metal screw to regulate pressure)

Thanks in advance

There is a spring in a pressure regulator that over time will weaken and either require adjustment or replacement of the regulator if there’s no adjustment. Additionally most fuel pressure regulators do have a diaphragm inside them so you may just want to get a new one ready
