Fuelab 6AN High Flow One Way Check Valve - 350 GPH

When you need to ensure fuel is only moving in one direction in your fuel system, a check valve is a crucial component. This one-way check valve from Fuelab is designed for high-flow applications, capable of handling up to 350 gallons per hour. It uses a 6AN fitting, which is a common size for performance fuel lines, making it a solid choice for custom fuel system setups.

The valve itself is well-built to reliably open and close, preventing backflow and maintaining consistent fuel pressure where you need it. Its simple, effective design means it won't add unnecessary restriction when fuel is flowing forward, but it will stop fuel from going the wrong way. This is particularly useful in systems where you want to prevent fuel from draining back into the tank when the engine is off, or to isolate different parts of the fuel system.
