I am having the same problem. Oil spilling all over the battery and beyond (Terrible design). I replaced the grommet with a new one, but it is still leaking like the president's diaper at the Vatican. Anyway, any chance you (or anyone) can guide me a little better on how to apply the plastic JB Weld? If I understand correctly, I need to remove, drain, clean, and dry the reservoir. Then scuff up the plastic around the outside of the hole and apply the JB. Is the goal to just make the hole a little smaller so that the rubber grommet has a tighter fit? That seems to make sense, but how narrow am it trying to make it? The grommet still has to fit in it. Or are we trying to make the grommet adhere to the tank so that the connection is no longer slightly flexible? I don't think we would want it "glued" together as it is supposed to allow for the play/vibration of the hose while in use. My goal is is do both methods suggested in this thread as this 15w-50 stuff ain't cheap and I'm not trying to continue on having the most lubricated battery. I will align the hose and secure with zip ties,w but I also want to make sure that I properly do the JB fix. Thanks for any help.
