I am looking into a return system. I currently have a gen 2 2.9 Whipple non crusher. Will be upgrading blowers most likely when I do fuel system to a new version 2.9 crusher or the 3.0 version. I know I need ID 1300's (Currently have ID 1000's), dual 465 pumps, FC3 controller. Dead head vs other way? Fuel rails in series vs parallel? -10 feed and -8 return? Is there a Fore kit that is complete with all fittings that has the crossover in the rear and is a neat and hidden install? I like the factory looking engine bay.
