I'm betting you've got a minute leak then. If you do lose pressure when you let it sit, try a few wraps of teflon tape around the connection where the macroline pushes into the fitting, if it doesn't lose pressure after this you know your macro's bad. If it still does you know to look elsewhere (o-ring seals, threads, etc.)
