Primer pump question( important)

Today i unscrewed my primerpump handle and started to pump it just to see how it works as i have never used it before. i noticed that on every upstroke a whole bunch of diesel flows out of the pump as though it is on top of the pump plunger? also the pump has a very shotr stroke, about 2-3 " is this normal? can some one explain how the primer pump works and is this overflow normal. i ask this because i want to change my filters soon and i dont want to be stuck with a broken primerpump and a bunch of air in my system!
i hope my description of the overflow was clear enough if not i will draw a diagram
thanks guys and girls.
