Assy, Vent A356000050

The authentic Air Vent allows air to enter the fuel tank as the level drops, so it does not create a vacuum within the tank, which would prevent fuel from flowing into the carburetor. The part attaches to the fuel line grommet on the tank. Installation is rated as "Easy" by customers and requires pliers. If broken from general wear/fatigue, the engine will be starved of fuel and will struggle to run or not run at all. If this happens, it should be replaced. The vent is white and plastic. Refer to your make, model and diagrams to ensure it is the right part for you.
