Merc engineers were *brilliant* when they did away with the spring loaded method and went with a fixed lash. Needs more tools to set up properly but is mechanically much more reliable.
There might not be a problem, temps change at night. Could also be the gauge and/or fittings used may have the leak. That said I've never let one sit all night, after an hour I'm good and fill it back up.
How did the vacuum check out?
Pressure and vacuum test only need to be held for 15 minutes. Any longer than an hour and you're going to get 'false failures'...Like you have.
