Abstract: A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control valve is provided on a standpipe to control the flow of fuel into the standpipe. The valve has a component that has a first position at which any flow through the flow passage past the valve is insufficient to permit engine operation, and a second position at which a greater amount of flow through the flow passage is permitted by the valve in an amount sufficient to permit engine operation, and the component rotates about the longitudinal axis when it moves from the first position to the second position and from the second position to the first position.
