Thanks, here is the best photo I have - It shows the gas valve end fitting (the dryer is out of town at my inlaw's house.)
I also attached a drawing from the manual which clearly shows the compression nut by the pilot adjusting screw and the other end by the pilot burner. Both fittings are the same. The photo was taken with the tubing and nut removed. Must be 3/16" because its smaller than 1/4 and larger than 1/8.
I suspect the corroded tubing I removed was a replacement because it was a coil of about 30" of tubing bent at the ends to make the connections, not a neatly formed section like the drawing.
