This is confusing.. the Pressure PA on the cylinder in left is basically equal to your rho*g*h1 because it is the same gas and its pressure will be the same at all points once you open that cylinder..If its not the same pressure yet then it will continue to push the orange fluid up until it becomes stable and can't push further. Also, atmospheric pressure can't be neglected in an open manometer. How could you neglect 101.325 KPa which is a huge magnitude.
