run a long hose from the return line to a can/pan and turn the wheel back-and-forth or start the car. if you don't like it, don't do it, but it can be done.
if the possibility of "running dry" is uncomfortable to you then you can also submerge hose into a gallon of fluid, start the car, shut it off when clean fluid starts coming out the other side. that's a two person job.
