One inherent thing is that there is no inherent evaporative emissions system likely. In european models they vented to the atmosphere after a vapor condensing chamber. Anything brought into US compliance had to use a diffent system and I have seen many different aproaches.

The whole fuel system including evap system needs to be visually checked; mostly from underneath.
