This dip stick fuel gauge is specifically designed for the Cessna 172 Skyhawk with standard tanks containing 19 gallons of usable fuel.

Made of heavy duty clear plastic that resists yellowing, fading, and cracking. Easy to Use: Simply insert the Fuelhawk until it touches the bottom of the tank. Then place your finger firmly over the top of the opening to lock fuel in the tube. Remove and instantly see how much usable fuel in U.S. gallons is inside the tank.
