Like Reed above said, there are two hex screws on the side of the Kiki pump. The one near the bottom of the injector body is the drain, the level plug is just above near the middle of the body, and the threaded mushroom shaped breather / fill port on the top of the body where you fill it. Thei injector uses engine oil (15w-40 or 30W, etc., whatever you use in the motor).
