Mr. Ed, et al,
I fully realize the restrictions of the antique fuel systems and rules. Red Anderson was a great tech guy and was adamant about line dimensions (OD) but was fairly tolerant of use of better fittings and eliminating tight bends in fuel lines as long as you didn't try to BS him. He even tolerated using better tubing as long as it was the correct OD.
I miss Red and his friendly smirk when he asked...."exactly what are you trying to do here..?" Lotsa good Red Anderson stories.
My points about fuel systems were targeted to today's approaches where electric pumps and skillful plumbing are acceptable. Getting away from the antique systems should be obvious. Even then, lots of errors are committed by not paying attention to the basics of fluid flow.
