Got a 98 Force 40 hp..noticed that there seemed to be some fuel leaking into the housing that appeared to be seeping out around the tube/nut at the bottom of the bowl. i took it off and noticed that the nut looks like it should have an o-ring or a gasket on it but it doesnt, rite now its metal to metal which I dont think will seal. I want to make sure that it does require a gasket/o-ring, what the part number would be for a carb gasket kit and where i can find it. Any help would be appreciated.
