If your FPR oso cannot stay constant.. better check a lot of stuff.petrol from engine bay? check fuel lines...Pressure not regular? Measure voltage to FPR.. or check fuel pump.. if voltage fluctuates, or the pump is not working properly/tersumbat.. can also cause the pressure become irregular....Could also be electrical gremlins causing all that stuff on the FPR.Have to check each and everyone for problems.. then change the setting of the FPR.. simply using the FPR to compensate for fuelling will inherently fail.Like others have said.. if pressure also cannot keep constant.. there's probably other problems.
