Thanks for the feed back. I just thought that the filler tube was vented and should have run out. Not thru the cap area. I am just glad that it did not run down the side of the cab because my painter said it would be very difficult to repaint. Show quality paint and can't get between cab and box without box removal. Well I will have to watch it very carefully on fill-ups. And be glad the running board looks as great as it does.
