For injectors, we went to Ford Racing Performance Parts for a set of its 30-lb/hr pumpers. Part number M-9593-BB302 gets you an EV6-style injector that will snap right into your factory fuel rail and harness. The plastic fuel rail crossover lines will need to be lengthened/replaced. Be sure to specify high-pressure fuel line when getting it from your local parts store. We went with a 5/16-inch line and high-pressure clamps.
