LML Gang,

I’m building a piston IV-P and am near ready to close out the first wing.  The kit I have came with 3/8” fittings for the fuel lines.  However, I seem to recall some of you changing that out for ½” lines and hose.

What is the wisdom on this?  Is the standard 3/8” sufficient or is ½” necessary?  ½” is certainly going to have less losses but will also have more weight and will be more work and cost to swap out.
