I'm really interested in this set-up. Perfect if the mechanical pump dies on an off-road trip. Can you give me some details on how you plumbed it to the carb and tank? Appreciate it. When operating the electrical pump do you run it through the mechanical pump to the carb or is there a secondary line? Also, I do have a leak-down problem on my Edelbrock Q-jet that this would solve.
