As I recall, I used a 1/8" pipe thread, 90 degree hose barb elbow. Push a plastic hose over it and run it into a clean container. You can keep the flow going while getting the air out. If you have say 2 quarts in your pressure ( sprayer ) bottle, you can work on the bubbles a long time before running out of fluid. Flow I think is the main issue. I was not aware Don had a brake lock in his system. That adds another thing to think about. The time I had problems made me take a different direction, and the pressure feed was simple, cheap, and works.
