Fuel return line
If running E-70 on an Evo 8 with 1300cc injectors and a 320lph pump, do you need a fuel return line? If so any recommendations on size etc? Tried a search, no luck, ty.

Your fine with stock stuff. I made 550 on a mustang dyno and I was still ok. I opted to redo the lines to and from the rail for the second stage of my build.
