In the fuel rail where the injectors are at there should be a small black plastic cap, slightly larger than a valve stem cap. That is the shrader valve for the fuel system. Wrap a towel around the valve and use a pointed object (like a small screwdriver) to push the shrader valve in and relieve the pressure. Make sure you are wearing eye protection though because there is a lot of pressure in there
