Filler Necks

Filler Necks are essential components in a vehicle’s fuel system, connecting the fuel cap opening to the fuel tank. A properly functioning fuel filler neck ensures smooth and secure refueling by guiding fuel efficiently into the tank while minimizing the risk of leaks or vapor escape. Typically constructed from corrosion-resistant materials, filler necks are built to withstand exposure to fuel and environmental elements.

The fuel tank filler neck plays a critical role in maintaining a sealed system, supporting emissions control and fuel system integrity. Variants such as the gas filler neck are tailored for specific vehicle configurations, ensuring compatibility with caps, sensors, and vapor recovery systems. Replacing a worn or damaged fuel filler neck is important for avoiding refueling issues and preserving system pressure.
