This AutoMeter 52mm mechanical boost gauge uses a patented Bourdon tube movement for precise, durable boost and vacuum measurement without electrical hookup. It includes 1/8" NPT fittings and a nylon line kit for plumbing, and perimeter incandescent lighting for dial illumination. The mechanical movement is emphasized for accuracy and longevity in demanding environments where a reliable, self-contained boost readout is required.
