This is an electronic American made gauge kit. The gauge is a dual faced gauge that will register your oil pressure as well as the water temperature.
Oil pressure measures 0-15 psi, the water temperature measures 100-260 degrees. The kit includes an electronic oil pressure sender and an electronic water temperature sender.
The gauge will fit any standard 2-1/16" gauge holder bracket (not included). The gauge will work on 6 or 12 volt systems, negative or positive ground!
Both senders mount using 1/8" NPT. If you want the gauge to be illuminated, you must purchase the illumination kit separately. 1928-31.
