Introduction
Some 2005 model year GX 470 vehicles may exhibit a condition where the fuel gauge does not display the correct fuel level. This condition may be caused by high alcohol content in the fuel swelling the suction tube and reducing movement of the fuel gauge sending unit float arm. The fuel pump assembly has been improved to correct this condition.
