AutoMeter - 2-1/16" Boost gauge 0-35 PSI Mechanical - 3604

This mechanical boost gauge from AutoMeter is designed for performance applications where monitoring positive boost pressure up to 35 PSI is required. It employs a high-precision Bourdon-tube meter movement (mechanical, so no electrical hookup required for the pressure reading) and includes all the necessary tubing and fittings (such as 1/8″ NPT connection and nylon line kit) for installation. 

The gauge features classic instrumentation styling with a black dial face (depending on model), high-contrast lettering, and traditional incandescent or other lighting for visibility. The 2-1/16″ size fits a standard custom dash or gauge pod.

Key Features

• Mechanical boost gauge (0-35 PSI) — no electrical signal needed for measurement.
• Standard 2-1/16″ panel size for easy fitment.
• Includes pressure tubing and fittings (1/8″ NPT, compression fitting, etc.).

Compatibility & Installation Notes

• Designed to monitor boost (positive pressure) up to 35 PSI — ensure your engine’s boost range is within this limit.

• Needs to be installed with the correct pressure feed / line; check for correct NPT port size and routing of the tubing to avoid kinks or leaks.

• Because it’s mechanical, ensure mounting orientation avoids excessive vibration or damage to the tubing.

• Verify your dash panel or gauge pod accepts 2-1/16″ (52 mm) gauge cut-out.

• Confirm lighting and electrical wiring only for the gauge illumination (not the pressure reading itself).
