My 1993 S4, 230K miles, has been getting dirtier (smog) and lower mileage. I
rebuilt the engine, turbo and replaced the fuel pump. Tested the FP
Regulator and fuel pressure.

The fuel system does not hold pressure. Next move is to test the injectors.

I had the injectors cleaned recently, but don't know if cleaning would do
anything about a leaking problem.

So what do you suggest for this situation:
	New fuel pump
	New fuel filter
	No diagnostics
	230K on fuel injectors
	230K on fuel pressure regulator
