How to fix PowerBuilt vacuum pump ?

[MotorHead]

Was bleeding my brakes and I guess I got some brake fluid in the pump itself. That POS little plastic jar that is supposed to hold the fluid so nothing will get into the pump won't hold any vacuum so it is useless. Anyhoo, anyone know how to take one of these apart and get it so it works again ? Or maybe you don't even have to take it apart I don't know http://goshopping.thestar.com/shop/p...d_1849742.html
