You need an airplane so you can talk to ATC like that
Besides what you listed, a way to connect the pump to the steering box. Also known as a hose. Depending on what pump you have, the pump end likely either needs to be 9/16" inverted flare or a GM o-ring fitting. In the former case I believe there is a Scout hose that will work (check with Admin, I think he knows the application) or otherwise if there is a hydraulic hose shop in your neighborhood- more likely if there is agriculture in the area- they can make up a hose for you or put a new one on the hose you already have.
Or you can get fancy and buy AN adapter fittings and Aeroquip hose from Speedway Motors.
