We're running 135+ with stock rail and adjustable regulator. 2 nozzles of alky, too. But, cutting and welding a fitting on the rail is no problem. Why not use a single -8AN feeding under the coil pack and two -6AN returns at the front?
Thanks! After more consideration I think first I'll get it running simpler with one feed like stock with -8AN and use the factory regulator for the return like stock before I go nuts with it, I have to get XFI etc probably too later. I found there are metric to AN adapters so later I can go from -8 or -6 to the metric/saginaw inlet and only maybe have to weld the driver side to cover the factory pressure regulator port and stick on a return off the back under the coil pack like Nick mentioned.
