I have a yz 400f and its leaking fuel from all around the bowl and possibly the AP. The bike sat for a little, and i believe the gasket for the bowl is bad. Is there a gasket kit i can by or a carb rebuild kit? any links would be helpful. Also what seals the AP its metal on metal? does gas go inside there?

If the accelerator pump is leaking gas around the rod, the AP diaphragm is ruptured.
