Abstract
A fuel delivery system includes a fuel tank having at least a main chamber. A reservoir is disposed in the main chamber. A fuel pump and venturi jet structure are provided in the reservoir. The venturi jet structure includes a jet inlet having a nozzle for receiving fuel from the fuel pump. A fuel inlet tube structure has a first end associated with the nozzle and a second end extending into a portion of the fuel tank. A mixing tube is in communication with, and downstream of, the jet inlet and the fuel inlet tube structure. An outlet is in communication with, and downstream of, the mixing tube. A length of the fuel inlet tube structure is greater than a length of the outlet, and the mixing tube is mounted so that an axis thereof is generally horizontal ±39.90 degrees with respect to the bottom surface of the reservoir.
