A fuel system includes a system inlet and a system outlet. The fuel system also includes a metering valve with a metering valve inlet fluidically connected to the system inlet, and a metering valve outlet fluidically connected to the metering valve inlet. A pressure regulating valve includes an inlet fluidically connected to the metering valve outlet, and an outlet fluidically connected to the system outlet. A spool of the pressure regulating valve is configured to fluidically open and close the inlet to the outlet. The pressure regulating valve also includes a control chamber on a control side of the spool. A pilot valve includes a return port fluidically connected to the system outlet, and a supply port fluidically connected to a line fluidically connecting the metering valve outlet to the inlet of the pressure regulating valve. The pilot valve also includes a signal port fluidically connected to the control chamber.
