So I'm just got the radiator funnel to bleed the air out of my radiator, but none of the attachments fit snug. Is this how it is supposed to fit? I'm just afraid its going to spill out. because its a bit loose.

 

Thanks to Rookie- everything worked fine. Looks like a few people looked into the thread, so basically he told me to use the bushing from a larger adapter and put it on the top side of the correct adapter between the adapter and radiator cap attachment, fit nice and snug and had no spills.
