Remember P0230 will be shown if request pressure is lower than actual - this could be to do with the high pressure side, it's just that it so commonly comes up when caused by lift pump issues...
But it's SO common to happen when driving normally...
I need to take a GOOD look at how the HDi low pressure side is supplied to see any potential issues...
IMO you need to be looking at much bigger pumps, you'd be surprised at how much fuel the HP pumps move, remember they move near enough their full quantity 24/7 - since the regulator is placed AFTER the pump... They use the fuel as their lubrication - that's the main difference, and notice they even have a fuel COOLER circuit, they bypass that much fuel!
Look into the Airdog FRRPs, they're 100gph pumps and adjustable pressure... If you're wanting decent power levels, I wouldn't be looking at much else.
Though I also think people should be getting Rail Pressure gauges, also inlet pressure gauges, even if you start to just log them on a laptop or something for diagnostic purposes... That would be enough to see whether you're getting problems...
