The Fuel System Pressure

30-48 PSI (Pounds per Square Inch)Vent the fuel tank vapors by loosening the fuel cap then disconnect the electric fuel pump relay plug, and start the engine . Allow the engine to run until it runs out of fuel and stalls.After spinning the engine over for a period of (30)seconds, turn off the ignition switch and disconnect he battery ground cable. Reconnect the electric fuel pump relay, and install a fuel pressure gauge in the fuel rail supply line. Secure the fuel tank cap, and reconnect the battery ground cable.With the ignition key in the on position, verify that no leaks are present and energize the fuel pump.This will bring the system to a stabilized fuel pressure that can be visually verified on the gauge.

It doesn't have a valve connector and you will have to add a T connector for the fuel pressure gauge.
