OBP Roll Over Breather Valve
OBP Motorsport Roll Over Breather Valve – AN6 & AN8
The OBP Motorsport Roll Over Breather Valve is a vital safety component designed to prevent fuel leakage and potential fire hazards in the event of a vehicle rollover. Installed either in-line within the fuel breather hose or directly onto the fuel tank, this valve automatically closes when inverted while still allowing the tank to breathe under normal operation.
By enabling proper ventilation, the valve helps avoid excess pressure or vacuum build-up within the fuel system, ensuring both safety and consistent performance.
