Thanks, Lynn. My A&P was keen on putting in better hoses and fittings to replace what is currently in there. He showed me some thin wall tubing already installed and how easily it will crimp and collapse.
Thanks for the instructions on the fitting installation and how to hookup the regulator. What would be your best guess as to what "P, T, H and G" mean?
