The fuel line from the regulator runs to a 180-degree fitting that attaches to bulkhead in the box. As you see from this picture, many other things have changed about this car. The amount of effort that has gone into this Camaro has been phenomenal, from the trick MSD ignition to the now functioning A/C, quick ratio power steering and even cruise control. The MSD 6-BTM ignition box also gets a boost reference from the back of the box and can pull timing out of the motor when under boost, all from a dial inside the car. With everything finally in place a day at the dyno is all that is left.
