These Affordable Aviation Fuel Vent Plugs (EDMO# FV38) are for 3/8-inch fuel vents found on Cessna 150, 152, 162, 170, 172 and 177 aircraft. These fuel vent plugs allow for proper venting of the fuel tank while preventing bugs or debris from entering the system. This is achieved through the oversized hole in the end of the black cap where the red cord passes through.
