PROBLEM TO BE SOLVED: To provide a resin fuel tube with superior heat resistance, light, superior in impulse resistance without causing fuel leakage and capable of being used at atmosphere equal to or higher than 130°C in an engine room or the like.SOLUTION: A resin fuel tube includes at least one resin layer. The resin layer includes following (A) and (B), and comprises a resin composition in which the mixing ration by weight of (A) and (B) is in the range of [(A)/(B)]=95/5-50/50. The resin layer has a structure where a soft structure (Y) comprising (A) comes into between crystalline structures (X) comprising (B). (A) is a polypropylene polymerized with a metallocene based catalyst. (B) is a polypropylene based material having a melting point of 137-160°C. |
