-10AN Roll Over Valve

The -10AN Roll Over Valve by Vibrant Performance is an essential safety component designed for high-performance fuel and fluid systems in modified vehicles. This valve serves as a critical overflow protection device, preventing dangerous pressure buildup and fuel sloshing in sealed tanks during acceleration, braking, and cornering. Whether you're running a turbocharged engine, custom fuel system, or track-focused build, a quality roll over valve protects both your engine and fuel system integrity while maintaining proper line pressure under dynamic driving conditions.

Vibrant Performance engineered this -10AN rated valve to handle high-flow applications while responding reliably to pressure and gravitational changes. The -10AN designation indicates compatibility with -10AN hose and fitting standards, a common specification in modern fuel system upgrades and motorsports builds. The compact 4.53 x 1.5 x 5.91-inch profile and lightweight 0.27 lbs construction make installation straightforward in tight engine bays. The valve's internal design prevents fuel backflow and tank overpressurization, automatically venting excess fuel back to the tank when conditions exceed safe parameters—a fail-safe mechanism critical for both street and competition applications.

Mechanics and engine builders typically specify this component when upgrading fuel systems for turbocharged, supercharged, or high-boost applications where tank pressure spikes become problematic. Installation requires routing the valve's inlet from your fuel system and outlet back to the fuel tank, ensuring proper orientation per manufacturer guidance. The -10AN Roll Over Valve is compatible with both carburetor and fuel-injected systems, and integrates seamlessly into custom fuel lines, making it a versatile choice for street rods, drag cars, road race platforms, and daily-driven performance vehicles seeking reliable overflow protection.
