AdBlue tank

I filled up with AdBlue and as I pulled out the nozzle a small rubber nozzle that was fitted on the end came off and went into the tank. As there is a sharp bend in the filling pipe it can’t be got at. Is there a filter in the AdBlue line anywhere that I can extract it from? Or any ideas? I don’t fancy leaving it in there and it breaking down and causing a problem. Thanks Steve
