Gasoline expires

Hello together, the following problem (Daelim S3 125ccm) after the full tanking. Under the scooter there was nothing thought about a small puddle and from work. There then on the work evening a light petrol smell found, but not looked more closely there are several two wheels there.. At home and the next day then a puddle was found. It is definitely petrol. Now I have seen that it is the connection nozzle or hose from the tank is leaking. https://www.dataparts.eu/… /fuel tank Have already removed parts from the running board, but I can’t get there. Looks like the inner lining has to be removed, but I can’t get it solved. Does anyone know if they have to remove the front panel!? Bzw. if this is enough then or if I am on the way to the wood!? Thank you for your help!
