-8AN Roll Over Valve

The -8AN Roll Over Valve from Vibrant Performance is an essential safeguard for high-performance fuel and fluid systems where pressure spikes or vehicle rollover scenarios pose a risk to component integrity. Designed for enthusiasts and professional builders working with custom fuel injection systems, turbo setups, and modified carburetor configurations, this valve prevents catastrophic fluid loss and contamination during sudden vehicle orientation changes. Whether you're tuning a track car, building a competition drag rig, or upgrading a street performance engine, the -8AN fitting size ensures seamless integration into modern -8 AN hose and fitting ecosystems.

This roll-over valve functions by allowing normal fluid flow during standard operation while automatically closing internal check ports when gravitational forces reverse—such as during a vehicle roll, hard impact, or inverted scenario. The -8AN port size (matching standard -8 AN adapter threads) makes it compatible with braided stainless hose, push-lock fuel lines, and compression fittings used throughout modern EFI fuel rails, return lines, and vent systems. Its compact design (3.54 x 1.5 x 6.3 inches, weighing just 0.16 pounds) permits installation in tight engine bays without requiring major bracket fabrication, and the lightweight construction minimizes parasitic weight on fuel system pressure readings.

Mechanics and builders benefit most from this valve when designing dedicated fuel cell systems, racing fuel systems with remote tanks, or any application where fluid spillage during rollover could ignite hazards or violate competition safety regulations. Installation is straightforward—simply splice the -8AN roll-over valve into your fuel supply or return line using standard -8 AN fittings and hose adapters. It pairs perfectly with Vibrant Performance's complete line of fuel system components and integrates reliably into both naturally aspirated and forced-induction setups where pressure stability and safety are non-negotiable.
