Weighted Felt Fuel Clunk

Fuel clunks are a must for aerobatic flying. It insures that fuel is always flowing to the engine because the fuel line will follow gravity inside your tank. Without one, you increase the chance that your plane may stall when flying inverted or performing different maneuvers. Installing a fuel clunk is simple to install and an investment that any serious pilot should make.
