Just standard practice for positive displacement pumps, use as thin a gasket as you can and still get a good seal on the cover plate. Another factor on pumps is to look for gear wear patterns on the cover plate; these, like a thicker gasket, will allow oil to cycle within the pump rather than being discharged, resulting in lost pressure. It was a common practice years ago to put some emery or crocus cloth on a piece of flat plate glass and surface the cover until the wear marks have been removed.
