I will be fitting this to a zetec black top as I'm using half an st170 inlet manifold and custom plenum, the st170 injector rail "apparently" doesn't have a fuel return line, instead it has a fuel pressure regulator to work with the fuel pump, I'd be looking to get rid of that as I don't think the zetec black top uses one or at least not the same one on the fuel rail, and I'll weld in the adapter in its place, can anyone correct me on anything that would prevent this from working. Thanks
