Brief Description: Red Cube Fuel Flow Sensor 3 Fire Sleeve
I did the annual on my Cherokee last week and noticed that my fuel flow transducer had fire sleeve around it, so I decided that was a good idea. I bought some from Aircraft Spruce and slid the RedBox in. Just fits. I made a slit for the wires. Some folks think firesleeve protects the hose. But it doesn't. It is merely a sponge to soak up any leaking fuel so it doesn't catch fire on something hot.
