Sometimes space is limited. The Auto Meter Quad Gauge provides a solution to limited dashboard space while providing a clean look. Individual Auto Meter air core meter movements for each function provide the accuracy and durability required by even the most demanding applications. Includes a single wire 1/8â€Â NPT temperature sender and a 1/8â€Â 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 60’s through mid 90’s GM fuel level senders).
