Did the tank leak fix this week. Now I cannot seem to get the flange with the green gasket back on. Lubed all metal and rubber with 5w oil, and added a rubber mallet. Sucker still will not seat. Suggestions??
Make sure all the little socket head set screws are flush or below the surface of the metal tank flange, then it will slip right in. Put the black gasket on last, it doesn't stay where it should be, if you try and put it on the tank flange first. Tighten all the little set screws evenly after you make sure the gas cap is lined up properly. Take your time, it was in there before you took it out.
