Getting the gas up to your engine so it can burn it and run is a very arduous job for your golf cart to complete. There are several working parts like the Club Car Fuel Tank Vent Assembly, the fuel pump, and the carburetor, to name a few. These items make it possible for the proper pressures to get created and get this job accomplished. If there is any extra air in the system, it can cause several things to happen, and none of them are good. First and foremost, too much oxygen is the primary cause of the fuel mixture being incorrect and putting the spark out on the plug that is in the cylinder.The golf cart fuel tank vent allows the proper amount of air to be introduced into the system. This ensures that the mixture is appropriate and will ignite under pressure created in the cylinder. We know this can be a confusing process.
