4 It's a good idea to use some stiff wire to make a simple pattern. The pattern will tell you about how much tubing you will need to cut off the roll. Plus, this is the stage where you can dream and try different routes. We decided to go around the valve cover and down the side of the head, staying on the outside of the top bolt hole since that is where the alternator mounts up. If we had our complete front drive accessories we would also look at routing the line behind the water pump, but as long as the bends are nice and smooth and we follow some sort of lines on the motor it's going to look good.
