The AutoMeter 52mm mechanical boost/vac gauge uses a patented high-precision Bourdon tube movement to deliver durable, accurate readings for boost and vacuum applications. It requires no electrical hookup, connects via a simple 1/8" NPT pressure connection, and includes 1/8" NPT fittings and a nylon line kit. Modern through-the-dial LED lighting improves nighttime visibility for clear readings.
