Please post the mode of Onan generator you have.
You may do a search on line and find a parts break down for the generator that shows how it attaches to the generator.
In my case there is a tube that is attached at the top and bottom that the oil dip stick goes through with clamps at both ends. There is a seal at the bottom.
You may check yours.
