PURPOSE: Provided is a polyamide resin composition excellent in gasoline-resistance, cold impact-resistance, flexibility, and appearance, which can be applied to a fuel tube system of a car. CONSTITUTION: The polyamide resin composition comprises: 50-95pts.wt. of a polyamide resin selected from nylon 6, nylon 66, nylon 6/66, or a resin having an amide group; 1-45pts.wt. of at least one impact reinforcing agent selected from EPM rubber, EPR rubber, EPDM rubber, maleic anhydride modified SEBS rubber, and etc., wherein the impact reinforcing agent has an impact strength of 30kg.cm/cm or more at -40deg.C; 0.1-20pts.wt. of at least one nylon plasticizer selected from a lactam and a sulfone amide or a plasticizer selected from a phthalate, an adipate, a phosphate, or a glycolate; 0.01-5pts.wt. of a nylon thickener selected from a multi-functional polymer, having at least two unsaturated carboxylic acid and maleic anhydride on the terminal of the polymer, and an oligomer type compound; 0.5-10pts.wt. of ionomer.
