Auto Meter Cobalt Gauges utilize blue LED lighting which makes for a brighter, more crisp appearance when illuminated. Auto Meter mechanical boost gauges come with 6 feet of nylon tubing and fittings to attach the tubing to the back of the gauge. Fittings for the other side of the tubing vary by model -- The Auto Meter "Vacuum/Boost" gauges, like those that read 30 In Hg/+30 PSI or 30 In Hg/+20 PSI for example, come with a "T-Fitting" from the factory which usually makes it easier to "tap your boost" from an existing line in your engine bay. However, Auto Meter "Pressure Only" mechanical gauges like the 0 - 35 PSI gauges typically have only a threaded brass fitting to tap your boost. We recommend our optional Boost Gauge Installation Fitting Kit, which includes a special T-Fitting, for easier installation of the "Pressure Only" gauges. Auto Meter electrical boost gauges come with an 8-foot wiring harness, MAP sensor, and T-fitting. This symbol indicates a mechanical gauge. This symbol indicates an electrical gauge.
