i don't know if the is helpful or not, but i had a leak once and it turned out the person that filled my tank did not tightened that screw fully that is used to get the air out of the tank before filling. i can't remember the name of that screw.
I do know. The pressure drops off within a few hours. I don't see how building or buying a manometer is going to help me find a leak. The high pressure in the pigtails is going to help charge the system with or without a manometer. If very slow leaks are acceptable and normal, then I am finished either way but I still cannot find them.
At this point I will check the bleed screws on the tanks. I did not think of them. Thanks.
