Filling rzr at gas pump

So I bought a new 2015 rzr xp 1000, on the way home I stopped at the gas station to fill it, made sure I got the trailer close enough. Tried to fill and it just kept clicking off, and I couldn’t get it to work, I was tired so I just left. But is there some sort of trick to filling the rzr directly from the gas pump nozzle?? Haha thanks
