Filler Necks
Filler necks are the structural tubes that connect a vehicle's fuel cap opening in the body to the fuel tank below, serving as the primary refueling pathway while incorporating anti-rollover valves, vent hoses, and vapor recovery system connections required by modern emissions standards.
