The AutoMeter GS 52mm mechanical vacuum/boost gauge uses a patented Bourdon tube movement for high accuracy and durability in harsh conditions. No electrical hookup is required thanks to the 1/8" NPT pressure connection; the kit includes 1/8" NPT fittings and a nylon line. Modern green LED through-the-dial lighting improves nighttime visibility, while the robust mechanical movement provides dependable readings for boost and vacuum monitoring.
