I just installed a new DW fuel pump and a new power master alternator. The alternator is set to about 14.6 volts. The problem I am having is I can't get the fuel pressure to less than 52. It doesn't move with the line on or off. Prior to this, the regulator was changing with the line on and off. We initially fired it up after the pump install (before the alternator) and the pressure wasn't as high as it is right now.
I have stock fuel lines and I suppose with the increased voltage I am getting problems. Do I need to change a return line? What happens if I drive the car with the fuel pressure this high?
