I looked around the garage floor and found the end of the hose. it does have a bulb end with a slit that no doubt is to keep out dirt, bugs ect and it was dry rotted. I am not sure how I could fashion one for the end of a hose. howeve, in my searches for parts I did see a site that showed a part with the bulb but as I did not know that was on my old tube I though it was the wrong part. I will go back ann look at that part and maybe order one if it is cheap enough if not I will use what I have and see it it works.
