This triple gauge kit gives high performance with a great racing look. The kit consists of a voltmeter, mechanical oil pressure gauge and mechanical oil/water temperature gauge. The pointer styling against the black 1 1/2-in dial face with white digits adds style and readability to its look. It has 12-volt internal lighting and is designed for negative ground systems. It includes gauge and mounting hardware but requires a hook-up wire for the voltmeter. It includes 72-in capillary tubing with 5/8-in national pipe thread, 1/4-in, 3/8-in and 1/2-in adaptors and 1/8-in and 1/4-in national pipe thread fittings.
