PROBLEM TO BE SOLVED: To provide a fuel system rubber hose superior in heat resistance, low extraction property and resistance to acid product with the decomposition of RME mixed light oil and superior in layer-to-layer adhesive force and durability. SOLUTION: The fuel system rubber hose comprises a tubular inner layer 1 and a rubber outer layer 2 provided in contact with the outer peripheral face thereof. The inner layer 1 uses the following (A)-(D) essential components out of which the (C) and (D) components are formed of a rubber composition blended at a weight ratio of (C)/(D)≤1/3: (A) iodine containing fluororubber, (B) organic peroxide crosslinking agent, (C) triallylisocyanurate, and (D) ethylene glycol dimethacrylate.
