Called Airline Hydraulics and placed order for SMC components. I ordered soft nylon and polyurethane tubing that SMC says will work with the one touch fittings to see if I like it better than the stiff nylon tubing provided in the Stein kit.
Created a spreadsheet with a list of drawings that are related to the firewall penetrations and mounting of firewall items. Completed review and comparison of documents and made notes so I don't have to figure this out again. Some things show up on multiple documents and there are some differences between revisions that might affect me. Now I have a good understanding of which things I can install now and which things should wait until I have the engine installed and the parts ready for installation. Also I have notes about which drawings and revisions to use for each of the components or systems.
