    has any one modded there return-less fual rail system ona 660cc to fit a external fuel reassure regulator in so they can raise the fuel pressure for when running more boost?

    bit stuck with this one, as all the older kei cars have a return fuel rail system but the copen being a newer car dose not have this.

    ive got a few options, plumb in a external fuel reg and external fuel filter, drill and tap a pipe in the top of fuel sender casing for a new return and crush up the intank reg so its wont return fuel that way

    get a fuel system of a avanzato, ie rail, reg and tank sender (doubt it will fit tho)

    run big ass injectors with a 255lph fuel pump and use a piggy back ecu to trim the fuelling back

    if any has over come this and modded there fuel rail system on there copen any help would be good
