5.5 Honda, dropped something in oil tank

I have a mower with a 5.5 Honda. I tried to use my oil extractor pump to change the oil but when pulling the hose out of the oil fill hole it got caught. When I pulled on hose the plastic connector/adaptor plug came off inside the oil tank. This is the reducer/adaptor plug that joins the larger diameter hose to the smaller one. I cant see it inside there, I tried tilting the motor on its side but it wouldn't come out. Is this likely to block/damage the oil pump or can I just leave it in there? Any advice would be appreciated, thank you
