Fuel Tank Vent Hose L0110020400A0 Automobile Fuel Ventilation Rubber Hose

This fuel tank vent hose, OE number L0110020400A0, is a rubber pipeline part for automobile fuel system. It connects fuel‑tank ventilation circuit to balance internal air pressure of fuel tank. Air flows into tank as fuel is consumed, and excess fuel vapor can be released properly during refueling or temperature rise to avoid abnormal tank pressure. It replaces original hose suffering from aging, hardening, cracking, oil leakage or air‑leak damage. Made of oil‑resistant and anti‑aging rubber. Its bending shape and port dimension match original part for perfect fit installation. It keeps ventilation circuit unobstructed and prevents tank pressure buildup and related fault warnings.
