What is a Check Valve?

A Check Valve, also known as a one-way valve, allows flow in one direction only, and prevents back flow (reverse flow). In the case of a fuel system, this valve ensures that fuel pressure in the line is maintained, allowing the engine to start faster even if the fuel system has not been sufficiently primed.
