ABSTRACT A method and apparatus of metering fuel to an engine wherein a continuous supply of fuel is provided by a pump to a fixed capacity chamber, and gas under pressure is admitted periodically to said chamber to maintain in the chamber a pressure not greater than the fuel pressure, so that fuel will flow into the chamber as long as there is a pressure differential between the gas in the chamber and the fuel supply. A delivery port in said chamber that is open for substantially the duration of the period that gas is admitted to the chamber, so that the fuel in the chamber at the time of admission of gas thereto, and fuel entering the chamber during the period of admission of gas, is delivered from the delivery port to the engine. The pressure differential between the fuel supply and the gas in the chamber is controlled in accordance with the fuel demand of the engine to control the quantity of fuel delivered each to the engine.
