Only thing I got from DI was the fuel fittings that go in the head. Other than that, I have Swamps injectors, the H2E can be had from various vendors(I had it already though), and the 3" intakes I got from the Ford dealer. I the pump and filter off my other truck, which had a small fuel system. But all the fuel system components were bought local from various shops, Parker Hydraulic store was the biggest help. I usually have a used SD fuel pump or 2 laying around, and the Fuel pressure regulator I bought from a local mustang shop since I was in there one day for something and they had it on display.
