Filler necks are crucial components that provide a secure and leak-proof connection point for funneling fluids into a vehicle's tank. They are designed to accommodate various filler nozzles and integrate seamlessly with a vehicle's fuel system. When choosing filler necks, consider their material composition, compatibility with specific fuel types, and ease of installation.
