Mechanical gauges cant "calibrate" themselves.
Also.. if you bought your gauge recently it should have came with everything you needed including some new things that autometer just started packing with their boost/boost-vac/vac gauges it's a little rubber deal that hooks to a Tee fitting and the other side connects to the nylon line, makes the install take litterly 2 min lol.
