where should i tap in and put the nozzle to spray. i see the throttle body and the boot coming up but it says 6- 18 inches is how far it should be from throttle body and isn't it after the mass air flow sensor. please explain where you tapped in to spray paul or pics would be amazing. also give me an idea of where to tap in for fuel, not too familiar yet with this engine but getting there little help in the right direction helps, thanks
