Aircraft Fuel Gauge specially designed for Cessna 172 Skyhawk with standard 26.5 gallon tanks.
Made of heavy plastic, clear and easy to use. Simply insert "Fuel Hawk" until it touches the bottom of the tank. Then place your finger firmly over the top of the opening to hold the fuel in the tube. Remove and instantly see a reading in gallons of usable fuel on a calibrated scale (For use on main and auxiliary tanks).
This fuel gauge is ideal when the pilot must carry less than a full load of fuel due to weight considerations, or for measuring the actual amount in the tank.
