The AutoMeter mechanical 2‑1/16" vacuum/boost gauge uses a high‑precision Bourdon tube movement for accurate, durable readings without electrical power. It connects via a 1/8" NPT pressure port and includes NPT fittings and a nylon line kit. Traditional perimeter incandescent lighting illuminates the dial for visibility, making it a straightforward, mechanically driven instrument for vacuum or boost monitoring.
