Hi, well, I decided to put some fuel additive into my fuel tank, it came with a seperate funnel, which you were supposed to attatch to the container to help pour the liquid into the tank without spillage. Being in a rush, I did not attatch the funnel on properly, and the funnel about 4 inches high with a disamter of a 2p piece fell into the tank! Being plastic, I hope it will just float about and not cause any damage? Please reassure me it wont do any harm, have to do a 400 mile round trip in the morning!
