The AutoMeter Stack Instruments mechanical boost gauge is designed for vehicles with no or low-powered electrical systems. With a broad measurement range from -30 inHg to +30 psi, this 52mm black-face gauge provides clear monitoring of vacuum and boost pressure for a wide variety of automotive applications. Its mechanical operation makes it suitable for vehicles operating on voltages other than 12 volts, vehicles equipped with a battery but no generator, and magneto applications with no electrical voltage available.

The AutoMeter Stack Instruments gauge uses a durable bronze Bourdon tube and a 270-degree sweep movement for responsive, dependable readings. Because it operates mechanically rather than relying on vehicle electrical power, the gauge is well suited to specialty vehicles, race cars, vintage applications, and other systems where conventional electronic gauges may not be practical. The black dial offers a clean, functional appearance that integrates easily into performance-oriented interiors.

Part Number atmST3112 includes a T-fitting for installation. The compact 52mm format supports versatile mounting in dashboards, gauge panels, and custom instrument layouts without requiring a dedicated electrical connection. Built for direct pressure monitoring, this AutoMeter gauge provides a practical solution for tracking intake vacuum and boost levels across naturally aspirated and forced-induction engines. Professional installation is recommended to ensure proper routing of the pressure line and secure fitting connections.
