Gas Line diameter

I know there are a couple of different diameters of gas lines running from the back of the car and wanting to know if you placed a caliper on the gas line what will the measurement be on the large line and measurement on the small line????? This would be on a 1968 camaro small block car,, thanks very much ,,gm_fan

The main fuel line is 3/8" (OD) and the smaller "return" line is 1/4".
