I pumped water through mine to clear out my pump. I also used a new piece of tubing at the end for the different fluids.

Thanks Scott... I was thinking that oil and water do not mix well and therefore not much oil would be removed from the inside of the pump and tubing. But I have no idea what other liquid can be used for cleaning it...
