Fluid pressure indicating apparatus which may comprise: a body assembly adapted for connection to a source of fluid pressure; an indicator assembly attached to the body assembly for indicating magnitude of the fluid pressure; a transducer assembly carried by the body assembly for translating pressure applied to one side thereof to linear motion at the opposite side thereof; and an amplification assembly carried by the body assembly between the transducer assembly and the indicator assembly for amplifying the linear motion of the transducer assembly to increased motion at the indicator assembly in predetermined relationship with the pressure magnitude of the source of fluid pressure.
