There should be a hose coming out of the top center part of the block on the V . If no hose is there a plug screwed in there? Normally that feeds the poppet valve on the lower starboard side of the block. If there is a hose feeding out of the top of the block, then splice in there with a TEE and connect the small hose and run it to the guage. DO NOT FILL the hose with water, it works on air pressure.
Tapping into the pee hole will not give you true pressure reading.

I don't know or have any way of altering your pictures. Should be easy to spot as it a hole/plug in the top center of the block. Not along the sides or back as you pictures only show the back, not the top. Your first picture shows a cross over tube from the thermostats, under that there is a black tube/line that probable goes to the poppet cover. That is the one to tap into.
