Its mich simpler than you think. Make syre the battery is unhooked. Once the upper intake is off, find the schrader valve (looks like a short tire valve stem), and bleed the pressure off. Then, undo the four bolts holding the fuel rail to the manifold. Carefully lift up on one end of the fuel rail, trying to keep the injectors in the fuel rail as you move towards the back. You can leave it all hooked up and move it to the driver side of the engine. Then unbolt the intake and EGR tube.
