My take on the subject is if an oil hose will flex because one end is attached to the motor and the other end is attached to a device on the firewall; flexing will occure due to differential movement thus the aluminum will work and eventually fail. That is the reason for steel fittings as I understand it. Bob Smiley N94RJ
