A lot of cheap quick fuel coupling in the market but warrning it does not work with presure basically does not work on any bike that does use a pump and sure not a race one. This Evotech coupling is made in Italy and as Evotech says goes till 83 bar of pressure. That is very high. This simple but brilliant accessory allows one to quickly, easily and comfortably remove the fuel tank. Indispensable on the races, very useful on every motorbike /mini bike, this product allows disconnection of the fuel lines by simply pressing a button. It has a double valve system which prevents the leaking of gasoline. Realized in a special thermoplastic resin (Acetal). extremely light, heavyduty and hydrocarbon-proof. Resistent even to high pressure (83 bar).
