You dont need any block off for the h2o passage, if you are running the RB intake, only the stock o rings and the intake blocks them off. Fuck the "T" for the omp, pre mix ! ! ! For the "throttle cable plate" just use an old alternator bracket and bend it to a perfect fit, very easy and works very well. You need a Fuel Pressure Gauge and get a good fuel pump like a Holley. I tried a generic that was supposed to push 6-9psi and wouldnt hold steady at 6psi had to switch to a Holley FP. You dont need any fuel lines, unless yours need to be changed out.
