Claim 0:
1. A fuel supply system comprising:
a fuel supply line to supply fuel to a combustion engine;
a fuel metering valve coupled to the fuel supply line, the fuel metering valve to control a flow of fuel through the fuel supply line to the combustion engine;
a throttle valve coupled to the fuel supply line downstream of the fuel metering valve, the throttle valve to bleed off fuel supplied to the combustion engine based on a pressure difference across the fuel metering valve, the throttle valve having a controllable position; and
a controllable servo coupled to the throttle valve, the controllable servo to control the throttle valve to set the controllable position based on a sensor output received from a sensor positioned with respect to the fuel metering valve, the sensor output indicative of the pressure difference across the fuel metering valve, the controllable position of the throttle valve set by the controllable servo to modulate the flow of fuel.
