Abstract
A draw and return tube assembly having draw and return tubes welded to a flange at a first end and crossed over each other and welded together at a second end. The openings in the tubes opposite the flange are positioned a distance apart such that fuel returned to the tank through the return tube is not immediately redrawn into the draw tube. The ends of the tubes positioned opposite the flange have a cross sectional area that facilitates placement of the assembly through a flange receiving aperture in a fuel tank such that the assembly may be installed within the fuel tank after manufacturing thereof. Welding of the tubes at their ends opposite the fuel tank provides for a stable assembly without the use of a separate securing device.
