it can be done at home but it's fairly tricky the eloys tank is located above the main fuel tank, the filling hose is just above the rear nearside wheel, the wheel and the arch liner will have to be removed to gain access unfortunatly the tank has no internal float the warning is computer generated between 50-60000 miles so it will have to be reset by a diagnostic computer if you manage to fill it also the particle filter is normally cleaned or replaced at this service interval
