Same here. Before drilling, I test fitted the pressure chamber getting as close to the tank as possible while not having the side of the tank interfere with me screwing the screw on the bottom in and out. You might want to drill the whole slightly undersize so the screw will fit snug. That way, it won't fall out during maintenance.
