The fuel guage screws onto the valve.

do i have to take any thing off to get to it
The port is on the fuel rail on the opposite side as the pressure sensor. Just like in the diagram. A scan tool that can read the data stream will also give you a pressure reading.

that is hard to get off
In nost cases it a black plastic cap just like a valve stem.
