I cannot give you a picture without pulling my fuel tank, but I can give you a verbal description.
As you probably know, the Atlas rocker lines terminate in banjos, one on either side of the head, on the TOP of the head. These lines are about 1/8 inch ID. Looking down from the top, (visualize the fuel tank removed), the lines resemble a horseshoe, the open end of the shoe is where the banjos mount to the head. At the closed end of the shoe, the lines tee to a straight section about 2 inches in length (IIRC). This straight section runs rearward dead along the bike's centerline, then transitions to a flexible tube. I routed the flex tube between the Amals ( do not remember if that was original, but it is cleaner). The flex tube transitions back to a rigid tube of diameter equal to the horseshoe part; this rigid section is about 3 inches long, and located at the banjo where the scavenge oil enters the oil tank. Originally the 3 inch straight section pointed vertically up.
HTH,
Slick
