Hi - I have just tried to fill my new Grenadier for the first time but cannot insert the spout due to a metal "door" closing off the hole. Using a standard nozzle (not hi-flow) which fits nicely into the rubber sleeve at the entrance but the "door" stops the nozzle going further than 20mm. The sales agent does not know what is happening and has gone home, presumably without looking at the pic I emailed. I have an early start tomorrow - and an empty fuel tank - any help would be appreciated.
