Fuel tank issues are very common, however, prepare to replace the tank anyway. The 8mm studs shear off on removal of the fuel pick-up/sender unit!
Figures for fuel pressure:
Approx 1.28 V - Average Voltage of Rail Pressure Sensor while the engine idling
Approx 4.29 V - Max. Voltage of Rail Pressure Sensor during abrupt acceleration
Approx 1.1 s - Reactive time of Rail Pressure Sensor during abrupt acceleration using a 'scope.
