I have removed my fuel tanks and coated them with epoxy. I am in the process of installing steel lines and was looking at previous posts and the service manual. I see in the manual and photos from previous posts that the small vent line on the front tank ( not the one with the fuel pick up and sending unit ) goes towards the passenger side and around the back of the rear tank and then to the vapor separator at the drivers side wheel well. Is there any good reason that it can not make a more direct path to the separator by making a loop on top of the tank and then connecting to the rear tank vent line and the separator? If there is something I am missing or should do differently please let me learn from your experience. If there is no good reason for the round about way I will make a shorter path and connect them together per the diagram for the vapor separator. I also remember something about making the connection between the lines up high by the separator. Any information to keep me from doing it over is appreciated.

Thank You
