This KUS Fuel gauge is uses a 240-33Ohm resistance system to function, and uses a moving-magnet to display the fuel level, resulting in a smooth, accurate needle reading.
This gauge is suitable for 12 or 24volt systems (a drop resistor is included for 24v systems) and is easy to install. This gauge uses a 52mm cutout, and will require 55mm of clearance behind the panel. This fuel gauge will suit panels 0.5 - 20mm in thickness.
There are two different lights inside this gauge. Simply wire the corresponding wire for either a yellow or a red background light.
