Description of Change: The fuel return tube assembly in the fuel filter lines has been replaced by a hose assembly. The hose assembly has a longer service life than the tube assembly because it is more resistant to breakage caused by vibration.
Adaptable As: The new 9N3040 Hose Assembly and 307946 Elbow are a direct replacement for the former 1W9271 Tube Assembly and 307941 Elbow when used in the 1W9267 Fuel Filter Lines Group.
