SRI Fuel Safety Check Valve

The SRI Fuel Safety Check Valve is designed to improve fuel system reliability and safety in race applications. The valve opens when the engine is running, allowing fuel to flow freely through the system. When the fuel pump is not operating, the valve instantly closes to prevent fuel from siphoning out of the fuel cell.

Unlike many competitor valves that restrict flow and cause pressure or volume issues, the SRI valve is engineered to deliver higher flow while maintaining safety. Enlarged reliefs on the internal piston provide increased fuel volume, allowing the valve to open fully at just 3 PSI. This design often eliminates the need for a high pressure fuel pump and external regulator.

Built with lightweight construction and #8 AN fittings, the SRI Fuel Safety Check Valve is a direct bolt-in replacement for common competitor valves and is approved by multiple major touring series.
