[ATTACH=CONFIG]541150[/ATTACH][ATTACH=CONFIG]541151[/ATTACH] I recently replaced my pick-up with a stainless tube with an I.D. of .48 which is just about the same as the I.D. of -10 line. When I hear people talk about 3/8" or 1/2" fuel line I often wonder if they are talking about I.D. or O.D. I always thought -10 line was 5/8" I.D. but everything I have purchased for my set-up in a -10 size measures approx. .48" I.D.
