I havd a KG Parts primary fuel rail for a 20b that i'm not going to use now. It won't work with the 550cc fc top feed injectors without a little moding to the plates. I also have the 3 KG Parts injector spacers to use the top feed injectors in the primary spot on the 20b. $125 shipped. It's all new stuff. I temp installed it to see if it would work for me.
