Just take the cap off of the shrader valve on the hard fuel line by the intake, and use a rag and a pen to push in the valve. That should do it.

If your car has been sitting for a while, the pressure ussually goes down so you won't need to relieve it. After you finish your work, prime the system by cycling the key to on then off a few times. Then check for leaks, and start the car.
