If I plan to put 550cc injectors, safc, and a lexus afm do I need a fuel pump. Ive heard I do and Ive heard I dont any opionin would be nice. If so which fuel pump would be good for this setup. Note I have intake, exahust.
I would get the pump before the 550's. If you get the 550's or the pump, you'll need an adjustable fuel pressure regulator (afpr) too. It's a good idea to do all these at the same time, but if you're tight on money, get the AFM, fuel pump and regulator first. The 550's are really not necessary until you decide to push the boost. The best pump is the Walbro GSS-341.
