HI!
the Inner Diameter of that Hose is not 4mm, maybe it will FIT and FUNCTION!?, but a 3.2mm ID hose is to prefeer.
there are lots of diffrent hoses u can buy, one of them is Gates GSL-32 Universal Fuel hose, another is "viton" hoses which we use here in Sweden often! especially in cars with the injectors under covers and so on, because of the temperature.
hopes u have found the right hose!
