Genuine Briggs and Stratton replacement part, it includes the Diaphragm and Diaphragm Gasket.
The purpose of the Diaphragm is to draw out fuel into the engine.
The diaphragm is forced inward by ambient air pressure.
The diaphragm is connected to the needle valve and as it moves inward it opens the needle valve to admit more fuel, this replenishes the fuel as it is consumed.
As fuel is replenished the diaphragm moves out due to fuel pressure and a small spring, closing the needle valve.
Most manufactures will have rebuild kits that contain new Diaphragms in them.
