Sometimes space is limited. The AutoMeter Quad Gauge provides a solution to limited dashboard space while providing a clean look. Individual AutoMeter air core meter movements for each function provide the accuracy and durability required by even the most demanding applications. Includes a single wire 18 NPT temperature sender and a 18 NPT oil pressure sender. The voltmeter reads from 8 - 18v on negative ground electrical systems and fuel level resistance range is 0 ohms empty to 90 ohms full (compatible with Amid 60s through mid 90s GM fuel level senders).
