AutoMeter - 2-1/16" Boost gauge 0-35 PSI Mechanical - 4904

This mechanical boost gauge is designed to monitor positive boost pressure up to 35 PSI in turbocharged or supercharged engine applications. It utilizes a precision Bourdon‐tube meter movement—meaning the gauge reads pressure via mechanical tubing and does not require an electrical signal for the primary reading. A 1/8″ NPT pressure connection is used, with nylon tubing and 1/8″ NPT to 1/4″ NPT adapter fittings included in the kit.

The gauge features a standard 2-1/16″ (≈ 52 mm) mounting hole size, making it compatible with many aftermarket pods and custom dashboards. The performance‐styled dial provides clear, accurate readings in a compact instrument format. Installation is straightforward: mount the gauge in the proper cut-out, connect the supplied pressure tubing and fittings, and ensure the tubing route avoids kinks and extreme heat/vibration zones.

Key Features

• 0–35 PSI positive boost range for performance engines.

• Mechanical (Bourdon-tube) movement—no electrical drive required for the pressure reading.

• 1/8″ NPT pressure port with included fittings and tubing kit.

• Fits standard 2-1/16″ gauge hole.

• Designed for use in turbo, supercharge, or high-boost applications where accurate boost monitoring is critical.

Compatibility & Installation Notes

• Confirm your intended boost range is within the 0–35 PSI domain—if your system sees higher boost, a gauge with a higher range is recommended.

• Ensure your mounting location supports a 2-1/16″ gauge cut-out and that the panel depth and clearance suit the gauge body.

• Route the tubing to the pressure port securely, avoid sharp bends or heat, and secure the tubing to avoid failures or inaccurate readings.

• Because this gauge is mechanical, no electrical sensor is required for the pressure reading—but the gauge may still require illumination wiring for the pointer/back-light (depending on model).

• Prior to installation, verify all pressure fittings and adapters are tight and compatible, and bleed any air in the tubing to ensure accurate reading.
