Does anybody know what the fuel line size is that comes up from the rear of the car and attaches to a push-on fitting and a rubber line that runs to the fuel rail. I want to replace the rubber line with a braided hose and assorted -AN fittings, but the hard line is less than 3/8 and greater than 1/4. I'm sure it's not metric, but maybe it's the inside dimension of the line that designates the size. I know that is the way with rubber lines.
