Happened to me aswell, located and fixed the
problem using a lift. Apperently a hose,pcv or some cable(was not there so could not really picture it when being explained to me) was laying flat on top of the fueltank making the rattle noises. They used a ziptie and a predrilled hole above the tank and secured the hose.
Hope this helps!
