A fuel delivery system for removing air from fuel delivered to an engine, and particularly a diesel engine, includes an engine, a primary water separation filter, and a secondary air separation filter. The air separation filter is located downstream from the water separation filter for delivering substantially gas-free fuel to the engine. The air separation filter includes a vessel, a fuel inlet into the vessel, a fuel outlet leading to th e engine, a fuel return discharge leading to the fuel tank, and a filter cartridge including filter media presenting numerous small openings therein for permitting the passage of fuel therethrough but screening out bubbles entrapped in the fuel. As the bubbles are trapped on the screen, they float upward to the fuel level and then spill over the upper margin of an upright tube within the vessel leading to the fuel return discharge and then to the fuel tank so that only substantially gas-free fuel is delivered to the engin e.
