I'm trying to figure out may new EFI setup. I want to run the fuel rail crossover at the front of the motor and hook the supply and return at the back since my fuel and return lines termite at the middle of the fire wall behind the manifold. I can make it work nicely if I can move the heater hose connection to the rear of the manifold. It just so happens the nice folks at Edelbrock made provisions for a rear crossover or something. Looking at the provided pictures I should just be able to drill and tap it? I don't need a ton of heat, just enough to defrost the windshield at a rainy event.
