PROBLEM TO BE SOLVED: To provide a rubber composition which is based on a blend material comprising NBR and an acrylic rubber, has good fuel impermeability, resistances to heat, amines, and sour gasoline, low-temperature properties, etc., and can be excellent in electric conductivity and to provide a fuel hose for automobiles made therefrom. SOLUTION: The rubber composition is based on a blend material comprising 70-30 wt.% NBR having an AN content of 46-52 wt.% and 30-70 wt.% acrylic rubber having an acrylonitrile content of 10-15 wt.%. The acrylate component of the acrylic rubber comprises an alkyoxyalkyl acrylate; and/or the blend material contains 10-25 pts.wt. (based on 100 pts.wt. polymer component) plasticizer preferably having an SP value of 8.8 or higher and a mol.wt. of 550 or lower. The fuel hose for automobiles is made from the composition.
