Volvo Fuel Tank Overflow Valve
Did you know the Volvo Fuel Tank Overflow Valve exists to help regulate pressure fluctuations inside the fuel system, especially during thermal expansion or sudden vehicle tilt? Even when the tank is not full, temperature shifts or uneven road surfaces can cause internal buildup. This part helps redirect that pressure appropriately without triggering leaks or vapor release. The Volvo 21458307 connects directly into compatible Volvo truck models and interacts with the tank system without complex wiring or adjustments.
