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. A damaged or corroded filler neck causes fuel odor inside and outside the vehicle, difficulty seating the fuel cap, fuel cap warning lights on OBD-equipped cars, and potential fuel leak hazards that demand prompt attention.
