Yes, if it's the bowl drain in the bottom, you might need a new bowl. The drain screw is a metal/metal seal. The taper on the screw seals against a mating taper in the bowl. If this as has been overtightened and buggered up, you'll have to polish any imperfections on the sealing surface in the bowl, which isn't real easy.
OEM parts are still mostly available. Rocky Mountain ATV, RonAyers, and BikeBandit are common sources. Unfortunately I don't see the just the bowl available as a separate part so you may have to go the salvage yard route to find one, if you need it.
This shall pass, be still and know.
