Depressurizing the Fuel System

I’m replacing the stock fuel pressure regulator in the eclipse with an adjustable one. This will not only let me adjust the base fuel pressure to compensate for higher boost if needed, but will also prevent larger fuel pumps from overrunning the regulator and causing a rich condition. I’m planning to upgrade to a 255 LPH fuel pump from Walbro in the near future, and that’s known to over run the stock fuel pressure regulator. ┬áBefore I begin, I need to depressurize the fuel system. This will prevent pressurized fuel from spraying everywhere when I begin disconnecting the fuel system....
