question on fuel pressure kit hook up...

[V6-Sauce]

I have the kirban fuel pressure kit to hook up directly the fuel rail without removing the factory port. Question do u to depressurize the fuel system before installing this kit and how's is that done?

Unplug the fuel pump connector under the back bumper while the car is running and wait for it to stall. Install pressure gauge. Done.

Install the gauge before you crank the car up that day. Very few cars hold pressure overnight.
